What's your most expensive moment of stupidity?

Cheer me up MN.

I visited DF for the first time since moving a loooong way away on the train this weekend. The train fares were over £200 all in but worth it to see DF. Raced to the station today to get the connecting train home and realised the return journey I booked was, in fact, yesterday. Minutes to spare and only first class seats available. £198. So my two days with DF cost me over £400. What an absolute wally! Am trying to channel my inner Love Islander and just say "it is what it is" (and obviously being grateful I actually had the money in my account to buy it). I was trying to think back and I think this is probably my single most expensive incident of stupidity (the one time the waiter accidentally charged my card €300 instead of €30 not counting as that was his fault).

Tell me yours while I drink my fifth cup of free tea.

Not a massive mistake, not vastly expensive but one year my DFIL gave the two step kids £75 each in cash, for christmas. Stepson put his straight into his back pocket. Stepdaughter left hers in the envelope. You guessed it, it got thrown out with all the wrapping paper. By me blush

Exactly what my late OH did with the cash given to our daughter by his mother, he was obsessive about getting rid of all the wrapping paper and when she couldn't find her envelope he had to empty the bin onto the garage floor to find it. Naturally, it was all her fault for not putting it somewhere safe.

We didn't realise until the rubbish was gone. So DFIL replaced it, despite me saying I would. I felt so bad. Always make sure now before throwing stuff away. Always.

Ordering concert tickets for my son and his girlfriend for their favourite artist when I was drunk. Cost me approx £300. Woke up to a text from his girlfriend thanking me and I didn't have a clue what she was on about Confused

Missed a plane because I can't read a 24 hour clock. I rocked up at 5.15 to be there 2 hours before my 7.15 flight. Which was actually a 17.15 flight. Cost me €50 to change and then my bag was 13kg over weight so they charged me €260. What a day

This is a near miss but seemed fitting - last night, goes in the back of the car to clear the car crap out that just acquires when you have kids.

Woke up to a text message off my neighbour - left both back car doors open. When I went to shut them, I'd also left the car key on the back seat. Brand new Audi Q2. Could have ended very differently! My husband is a calm man but he was tested this morning...

Bought a racehorse that had been neglected (should have been free the state of him!) cost £1500 to buy, £500 to buy rugs for, £4000 in bets bills, £2000 in saddles/equipment plus £1000 for a friend he’d be happy with as he hates our other horses! A costly mistake but he’s now 18, finally fit and healthy all in time for my little one (due in 2 weeks) to learn to ride on. A costly but very much worth it mistake!

HummingBeeBox · 19/07/2021 17:40

I just paid £1.99 for a single tiny pritt-stick from the local post office as it's too hot to drive to the nearest town. Worth it

We paid loads for a hands free set to be fitted to the car only to realise it we super easy and we could have bought and fitted it ourselves for £50 rather than £200

Oh God - the list is heartbreakingly long - absolutely beautiful cashmere cardigan - second time worn put in too hot wash and shrunk ( much younger then!) ; fell asleep on train returning home after Christmas at parents and woke to find my bag of treasured Christmas gifts stolen ; paid a shyster garage small fortune THREE times to repair engine problems on a Citroen Berlingo because it wasn’t old - they kept messing up and it ended up with us stuck on the M25 in snow and vehicle being worth not much more than scrap. Oh and ripped off by builders whilst I was pregnant and in hospital so couldn’t supervise that they were actually doing what they said 🥺😱😭( on the plus side have also been incredibly lucky and fortunate with many other things!! )

Booking cheap flights back from a week in France, to travel the day before dd was due to start in Reception.

Bit of a race to the airport due to traffic, thought we’d miss the flight. Rushed in, explained to member of staff and she shuffled us to the front of the check in queue and explained our predicament to the woman at the desk. Both looked doubtful, but made a call and said yes ok we can just about do it. Handed her tickets and passports and she looked at them, then said ‘I’m sorry, there’s a problem…you are booked on the same flight but tomorrow’. AAAAARRRRGHHH.

DH came skidding in from dropping off the hire car and I explained. I thought he’d be fuming, but he laughed. Then tried to book on another flight but they were all full or thousands of £££. Ran downstairs to the train station booked us on a fast train to Paris and the last Eurostar back that night at horrendous expense (£700). Dashed across Paris in a taxi at rush hour and just made the check in for the train. Dd did make her first ever day of school though Grin even if I aged several years getting her there and was paying off my credit card for a long time.

Sent an expensive bouquet for Mother's day - to myself. I was so touched when they arrived, until I realised I had paid for them myself.

£50. So much money to me. And nothing for my mum on Mother's Day! I then obviously had to reorder them for my mum!

At least they were beautiful flowers!

csigeek · 19/07/2021 17:51

Most expensive, probably putting unleaded in a diesel car, £80 tank of fuel plus about £125 to drain and clean and then another £80 to fill it back up with diesel (which I appreciate I would have spent anyway filling it up properly in the first place but it still irked me)
Most recent….booked tickets to peppa pig world last night, for the wrong date! Cost me £20 to change them to the right date 🤦🏽‍♀️

It takes a looooong time to clear up the mess from a barely used 5l can of paint that’s spilt in the boot of your new car. And it’s never the same again. 😢

Ddot · 19/07/2021 18:01

Just after lockdown took my car for service and mot, thinking it would pass and it was hard to get in anywhere else. It didn't pass and cost a fortune 🤬 bloody covid

jules0607 · 19/07/2021 18:04

Aye, but it was down to the conveyancer to warn you. Not your fault xx

Lndnmummy · 19/07/2021 18:05

Dropping car key in the drain. Last car key. £520 for a new one.

Awwwww bless your heart, you will laugh at it one day 💐

I bought my house 30 odd years ago and offered the full asking price as I was just fed up with viewing, sellers pulling out, surveys being horrendous etc. Only to find out 6 months later the sellers had accepted an offer of 15k less but the buyers went awol!

I parked up against a tree stump (which was put there to prevent people parking!) and thought ‘I must remember that stump is there when I leave’. Ran in to pick dd up from school, rushing to get back to work, came back, forgot about the stump. Drove over it… it got stuck on bumper. Made a split second executive decision to drive over it to prevent ripping off the bumper. Destroyed the entire car. Oil dumped everywhere, exhaust pulled off, gear box destroyed. It was so bad the RAC couldn’t even tow it.
It was a brand new BMW 😩
That was an expensive mistake.

When my Dad died our mother decided she couldn't afford to keep paying the insurance premiums for a policy that would pay the inheritance tax bill when she went! (She could, she never grasped how much he'd left her.) I wish I'd taken over those payments, they weren't huge. As it was, we had to pay over £100,000 IHT when Mum died the following year. You live and learn.

CookL · 19/07/2021 18:23

My husband borrowed my car and kindly put a full tank of petrol in it for me. It was a diesel car 😂😂

tillytoodles1 · 19/07/2021 18:24

I had to buy a new fridge freezer after my old one broke. All the food was ruined so I threw it away. I got the new one delivered but that wouldn't work either, until the delivery man said it needed to be switched in at the wall.
I plugged the broken one in and that worked too and I realised that I had accidentally knocked the switch and turned it off.

DM made the most expensive mistake of her life when she married her cocklodger and all round knob of an ex. Cost her half the value of her house and more in divorce proceedings as he didn’t have a bean to his name. That’s a mistake she won’t make again!

Justcashnosweets · 19/07/2021 18:31

We booked a very fancy wedding venue with a £1000 deposit. I fell pregnant and then realised the place would be completely unsuitable for children and babies so we cancelled and lost the depost 😭 we still havn't got round to getting married!

After drinking margaritas, I Bought 2 tickets to a David Guetta Gig at the O2 in Leeds, I was 60 years old at the time, stood at the back, watched all the 20 years having a great time, left when they started crawling on the floor to get to the toilets, thoroughly enjoyed myself but never again

Bananalanacake · 19/07/2021 18:34

HummingBeeBox - I feel your pain, my DD has got through a whole tiny pritt stick in 3 days just by gluing bits of paper together. Tedi"s own from now on.

RH1234 · 19/07/2021 18:40

Going into business with my "boss" at the time. She did nothing beneficial to the business and cost me £10k to get rid of.

Whilst stupidity going into business with, definitely the best £10k I spent, the one time I can say Covid helped. (Gave me an excuse to under value the business!!)
