I could probably post this in relationships but I need a quick response and so have braced myself and put this on AIBU...
My friend does not have a car and I do. She has another much closer friend who lives in the sticks with a new baby who I don't know.
The cost of taxi's from here in town to out in the sticks and back later would be £18, my friend asked me if I would do these trips for £10 so she could visit her other friend. I agreed. I was poorly that day so my DP drove her, which is fine, she knows DP just as well. Anyhow she didn't even offer him the petrol money and never mentioned it to me again. It actually costs about £8.80 to make that trip in my car, and more than £10 in DP's, but to be fair it wasn't her fault DP took her, it was my last-minute sickness that caused that, so I still think £10 is fair.
Then the other day she wanted taking to the next town (our town is tiny and most facilities are elsewhere) so I did that. This time I asked for the petrol money, she said she didn't have it and could she see me for it later. I said yes. Again this was a tenner, agreed in advance. Actual cost to me this time £7.90.
Two days later she invited me out for lunch, and paid for me, but this cost her £4-£5, it is a cafe we use a lot and so I know the prices well. By this point I am at least £11.70 out of pocket whichever way you add it up and she technically owes me £20 because lunch was not meant to be a repayment, just lunch (It was just her turn, we sort of take turns getting lunch and don't really keep tabs on it, it's just a friendly thing).
Yesterday I took her to her friends in the sticks again, £10 promised and accepted up front. This time as she was getting out the car on the second trip I asked for petrol money and she said she only had £5 and gave me that. So now I'm £15.50 out of pocket and she technically owes me £25.
I understand she might not be able to afford it, but she doesn't drive out of choice. She says driving lessons scared her. We are both equally hard up (means tested benefits) and she offered these sums herself.
In January she had an early MC and had to go to the early pregnancy unit for emergency scans. I took her. The hospital is so far away that this cost me about £20-£25 but it was an emergency and that's what friends do so I refused any suggestion of petrol money for that. For an appointment then yes, I would have, but not a life/death emergency. It is since then that she has been avoiding giving me what she promises and I have been out of pocket.
I'm meant to be seeing her later. I am quite annoyed but don't want to rock the boat because she can be firey. That said, AIBU if I never give her a lift again (except life/death situ's of course because I would do that for anyone). And AIBU if I give her excuses as to why not?
