I did that to asdas self checkout machines, a few 5p, 2p, 1p, then after around £5 of loose change the machine was starting to jam and it had to be opened up.
I took a temporary Christmas job in retail. The shop was in a pretty deprived area. I was next to the Coinstar machine. Many of the people who used it had obviously saved their change all year to pay for a big Christmas shop. No way they could put all that in the self serve.
I think the lesson is not to wait until you have enough change to fill a wheelbarrow! If you use it up each trip, it's not a problem - plus you can always put in 68p (or whatever) and then pay the rest by card.
I still think it's massively cheeky of them to give you a 'guideline' of how much you can get from a certain sized bag, but they include £1 and £2 coins in them - how are they 'spare change'? Maybe it's just my interpretation, but their advertising seems to work on the 'understanding' that spare change is basically useless 'leftovers' that thy can magically and munificently make into something valuable again!
I do feel for those in the deprived areas who have saved it up all year. It's the same principle as Farepak (and similar companies that are still going), where they make out they're helping you to save and make your money go further, when they're actually exploiting the poorest people by taking commission on their meagre savings and/or forcing you to buy from their catalogue, without being able to shop around and find more competitive prices. Vultures, really.
A friend on moving day, caught her dh removing lightbulbs. She made him put them back.
It's precisely because of people like him that fixtures and fittings forms now tell you that you must leave lightbulbs. It's almost embarrassing for the rest of us that they need to spell it out. It's a really nasty thing do: for maybe £20 worth of bulbs (even swap them for the cheapest ones you can find, if you must, as long as they work) in the context of hundreds of thousands for a house sale.
Your buyers (maybe with children) arrive at their new home, hugely busy unloading and all the associated work, it starts to get dark, they have to find time to go out to buy bulbs in an area where they may not yet know where the shops are or what kind of bulbs they need. It might sound smart but it's actually such a cruel thing to do.
House share in London, we'd often get a pizza delivered that was £9.99.
I took £5 off my housemate and gave the delivery guy £10. The next time my housemate said, "I paid £5 last time, so it's my turn for the change"
So that means that, when you paid, you would hand over a tenner yourself and wait there for him to give you a penny change? Or did you not bother, but housemate assumed you would?
I have posted this before but a man i know used to have only one light bulb in his entire house. He took it from room to room as he needed to. He was an accountant on a good wage, just extremely stingy.
What is it with misers and lightbulbs?! He can't have been a very good accountant, as he would have realised that, overall, he wasn't saving himself a single penny for all of his efforts.
A bulb in each room - whilst a slightly higher initial outlay - would in total last for the same amount of time as one bulb moved around and in constant use. In fact, it's often the electric surges caused by constantly switching on and off that artificially shorten a bulb's life, so all of those extra spikes quite possibly ended up costing him more.
I agree with PP that avoiding waste is a very good thing (I also didn't see why eating 14 eggs instead of deliberately wasting them was a mean thing to do) - when the only 'loser' from your actions is the bin/landfill. The problem is when you expect your little gains to come at the expense of others and quite often step firmly into theft and/or fraud territory.
Pressing the last slivers of soap into a new bar or using your ragged old pants as cleaning cloths to save money is a wise use of resources; effectively (or actually) reaching into somebody's purse and stealing a tenner in no way counts as 'saving' it.
