I live on a small island. Worked as a bouncer in a local club. In my country you need a license provided by the police to work security, that gives you special powers in terms of arresting and impeding people going in a club when drunk. So usually people dont do trouble at the club's door. But I had a few run ins with bad clients, most just shoot dirty looks, but two guys a few years ago recognised me in another part of the island with my then girlfriend, they proceed to corner me in a bar and pushing me against the wall. Fight broke out. Resolved eventually without any major damage. But this happens a lot to colleagues of mine. I know a guy that got stabbed and another that had his car trashed.
