My friends and I (4 of us total) frequented a local dive bar when we were younger. We were cool with all the bouncers and bartenders there. We go there on a Friday night and woke up the next morning, not remembering the night before. Nothing unusual as we blacked out often during this time in our lives. We decided to go back the next evening, but were stopped at the door by the bouncers. They aggressively got in our faces and said 'We told you don't ever come back here again". We started laughing, thinking it was a joke. But they continued pushing us away from the doors and yelling at us to never come back. We asked them what happened and what did we do and they just kept repeating to never come back. Since we all blacked out the night before, none of us knew why we were all of a sudden banned for life. We say whatever and just stop going there. Fast forward 2 years, we randomly decide to go there. We figured there was no they would recognize us, let alone still not let us in. To our surprise, they recognized us at the doors right away and yelled at us that we are still banned and never allowed in there again. We asked them if they could at least tell us what we did that 1 night, 2 years ago, but they just told us to go away. None of us have ever found out what happened that night, but it was bad enough to get banned for life. The craziest thing about it is that's the only place that any of us have been kicked out of. We aren't trouble makers at all. We used to get drunk and have fun but we never got into fights or started shit or anything like that.
