A fairly new friendship.. went for a night out together for the first time. We were trying to take turns in buying drinks but had both had a lot to drink so might have not stuck to it towards the end of the night. Next day she messaged me with a screenshot of her bank account saying she feels like she might have bought more drinks and because she's broke, would I mind giving her money to cover for half of the night's costs.
I was a bit put out because I've never really come across anything like this and felt we had taken turns paying. I know I'm more well off than her but feel like if a friend knows she'll struggle to afford a night out she should either not go or communicate it beforehand where I then get a chance to offer to pay more if that's what I want to do. Also we'd had a disagreement during the night where she wanted to go to a nightclub where the crowd was 20 years younger than us and I wanted to go home. I insisted for long time that I didn't want to go but she kept pushing and in the end said she'd pay the entrance fee for both of us if I'd go in. Entrance fee for both of us was 16 pounds.
After her asking I checked my account and had spent a lot of money, although 10 pounds less than her. So really I shouldn't owe her anything with her having insisted she'd pay for that entrance fee. She still insisted it wasn't fair and that I went to the club as well and should pay the same as her.
I'm really not bothered about the money at all but more about the weirdness and pettiness of it and of being drawn into something like this. AIBU to feel a bit weirded out by this?
