I (early 20s, F) recently started a new job in a city where I didn’t have accommodation yet. Two of my closest uni friends live there together, and since I know them really well, I stayed at their flat for about 12 nights over the period of 2 1/2 weeks before moving into my own place. While I was there, I tried to be as considerate as possible. I went home whenever I could to give them space, kept things tidy, and brought my own food. We also spent a lot of time together, hung out, and even went on a weekend trip to one of their hometowns to celebrate my birthday (which I was invited to). I had mentioned at the start that I’d be happy to contribute something for staying with them. Yesterday, one of them texted me saying they wanted £300 for my stay. They explained they calculated it as if I was paying a third of their rent for the 12 nights. The thing is, they live in a flat with rent that’s way higher than I could ever afford on my own , their parents pay it for them, one of them doesn’t even work, and they both regularly buy expensive makeup and clothes. They know my financial situation is nowhere near theirs. I’ve already paid them £150, which I thought was more than enough to cover bills and any extra costs while I was there. £300 feels like too much especially since I probably would’ve saved money just commuting from home instead. What really bothers me is that it makes me feel less like their friend and more like I was just a lodger. If the roles were reversed, I’d never charge a close friend rent like that. I don’t want to damage the friendship, but I also don’t feel comfortable giving them another £150. So, AITA for refusing to pay the full £300?
