Friend 1 is having a birthday. Friend 2 is organising it (weekend away)
There is one additional person going Friend 3. I’ve never met this person ever (just calling her friend 3 for ease).
Friend 1 is paying nothing towards this. Friend 3 cannot pay until 6 days before we’re suppose to be going - so nothing has been booked.
Friend 2 has asked if I would contribute 50% of Friend 3s payment and she will pay me back.
Aibu to say no as I although I could afford it I’ve never met this person in my life so I have no idea whether I would get my extra £100 back?
