welshgal I am totally appalled at her FB status. She has shown her true colours and if I saw somebody post that about a friend, I would instantly unfriend them.
I can't see that there is any legal comeback for you, you were doing her a favour. It was up to her to sort alternative transport, and who on earth has £13K for cosmetic surgery, but can't afford transport!
All this because you refused to let her freeload off you. I hate driving on motorways, and if a friend takes me anywhere, then i pay for diesel, lunch, tickets to the event, all because I could not get there without them! or if I went by train it would cost a lot more, plus of course it is nice having my friend there!
You are not responsible for her actions. She needs to ask herself why no other "friends" stepped up to help her when you couldn't.
