Input: I just graduated last year and I remember this guy from the grade below me. I went down to the gas station to get snacks. He was there and he had $40 in gas but his debit card wasn't working and he didn't have any cash. When I got to the counter they let me checkout. He recognized me and he asked if I could help out. He said he'd pay ne back at some point. I had the money, but I said no. I really didn't trust him. I also had to pay for my own gas later that week and groceries. I also said no because he never treated me well in high school. AITA for not paying for him?
