The playground girls were all moaning they never go out anywhere and they've got no money - I asked them if they fancied a girls night out at the local Thai Restaurant, special 1 night event tickets �10, they all said yes definitely, I bought 5 tickets and now bar one they've all texted me today (the day of the event mind) and said they can't go becuase they are 'going to a cricket match' 'got too much work on' and 'can't get a baby sitter'. I'm really pee'd off, not only that, only one of them - the one that's going - has paid for the ticket as they all said they'd pay me back on the day grrrrr!
If you can't get a refund I would definately ask the ones who cancelled for the ticket money. Something similar happened to me about 3 weeks ago. It was one of the girls birthday at work and I was asked to buy the present two of them still haven't paid me their share, but put their names on the card etc.
