I have one or two+ from the same ex good friend.
I walked out of a high profile professional job due to constructive dismissal & maternity rights. I had been there at the very start as the companies only employee & had been part of building up a very successful business, so you can imagine this change. In attitude because I dared to have a baby stung like hell & this friend who I'd employed in a more junior role as she needed work, knew first hand what I had gone through.
She tended to duck & dive, had various jobs from cleaning to sewing for a stall holder in a market. She had been through fashion school, but had failed & couldn't cut a pattern, design etc, but it became clear that she thought she could & she saved up to set up a business herself ... all power to her for that, but it soon became clear she relied on fashion professional friends to dig her out of a hole, for over selling herself.
After losing my job, I took ex employer to tribunal & won a healthy pay out, I had savings too so had decided to take a couple of years out as I was burnt out. I didn't need, nor want to work for anyone at that time.
Friend rang me in tears, she was in a huge panic as had orders to do for a new client, that she didn't have staff who could handle the work. She begged me in tears to help, offered to sort out childcare etc, sobbed & sobbed that she'd been stupid & f* up her business by taking on work she couldn't handle... so I was a good friend & agreed to help her out this one time.
Arriving I had to reorganise everything as it was all no good & I had to organise her staff & sew too as no one else could do the more difficult stuff. I was ill, in pain with my back, so could have done with it & wished I hadn't bothered, but I was helping a friend.
Part way through the day her client came in whilst I was sat at the machine & was very chatty, thinking I was the new machinist, turns out now exGF (A) had actually used my CV to get the work... mentioning the company I had ran & A had briefly worked in a non technical role at for me, got the reply... oh you've worked for A before then as that's the place she set up & ran... gobsmacked wasn't the word. Really wish I'd told her the truth, but I was dumbstruck
A while later A was on the phone & I heard her cackling "oh yes Rockin is here working for me today, cackle, cackle, everyone works for me in the end, even the successful know it all's"
I was so shocked I tried to convince myself I'd misheard & let it go, but as soon as I got DD back I made my excuses & left, though not before I'd set the work up for her so it was now achievable
I hadn't discussed money with her as I thought in my stupidity that I was doing a good friend a big favour ... shortly after I received a check in the post for about 20% of my actual going rate😏... figured it worth the money to realise that friend was a CF & a c@nt
I later found out who she was talking on the phone... another mutual friend & I didn't mishear at all, she was shocked at the attitude too.
Same friend A had the nerve to ring again several months later, again crying for a work favour, no friendly calls in between ... so I pointed this out to her & said as she's only ever ringing me for work favours lately, best we kept it on a professional footing. So I'd be happy to help but at my usually consultancy rate, plus 10% to cover the previous underpayment & that would include telephone consultation too. Would she like me to start timing the call now with view to billing her... she nearly choked, said "oh I thought I could just ring you for a chat like old friends. I said yes of course you can, it would be lovely to hear from you any time, but any work chat gets billed. I'll look forward to hearing from you for a chat & put the phone down.
I didn't hear from her in over a year, until out of the blue, very early one Sunday morning I get a call... hey we're in town & want to take you out for breakfast as haven't seen you in ages, cool I thought... then came the punchline ... we are camping out of town for the festival & can't get into the shower block as it's heaving, so thought you wouldn't mind us coming round & using your shower 
I asked how many she was talking about... turned out to be 10 people... only 4 of which I knew😏... I repeated to her "so you want to bring 10 people plus you to my house for a shower at 7 am on a Sunday morning & you'll then take me for breakfast for a catch up as it's been such a long time since I last let you take the piss out of me... er the answer will be NO
Never heard from her again TF
