Havent been a bouncer in about 15 years but funny story from when I was, a guy I threw out and had to manhandle roughly (he was trying to hit me and other people) came back the next day, not to start trouble or get in again but merely to apologise and go. Seeing somebody genuinely sorry was a very rare experience. He said and I quote "I know I was a bit of a cunt and needed a slap, I know I'm banned, I was off my nut and just wanted to say sorry and no hard feelings". It stuck with me because he really meant it. It really doesn't go like that most of the time.
I never really saw people from the clubs I worked at in my day to day life because the clubs I worked were way far from where I live. On purpose.
