Is AUTHOR wrong in the post ? POST : So I went out with a group of friends and one of them invited a friend and that friend brought two other people. So three people we don't all know. No problem, we are just out for fun. So all night the three new people and our friend are throwing back drinks left abs right. So fast forward to the end of the night,  they didn't have enough to cover their bill and said it was our fault because we didn't stop them when they were getting smashed. I refused to pay +60$ because they are adults and I don't feel I have to pay for random people's bad choices. Plus I know she has a credit cars but didn't want to use it. Am I the asshole for not paying?  Idk they made me feel bad for not paying for the whole thing. I dropped an extra 20$ and went home.
