I've had a reasonable number of 'incidents' over the years and my behaviour has matured substantially – mainly triggered by one event in a club. in my twenties I was seriously into martial arts used to represent the country and that sort of thing, and quite regularly used to encounter jumped up pillocks (normally the uni rugby team) who liked to try it on.
Used to please me so much to take these guys apart, I viewed it as part of my training….never start it, always finish it type mentality. Then one day one of my good mates (also a top fighter) got glassed full in the face by a guy who he'd had trouble with a few weeks back, the guy just walked up to him, tapped him on the shoulder and glassed him. Needless to say he was/is still pretty messed up.
Kind of sobered me up alot. Now I strongly promote the get away from them at all costs, it really isn't worth it, you just don't know what the consequences might be.
