Personally, I think bouncing/security/doorman positions, whatever the local flavor, are among the toughest scenarios for applying your training. First let me say that I've worked off and on as a bouncer for over a decade, but not in what some of you would call a rough neighborhood. The worst I've had to deal with was broken beer bottles and pool sticks, no guns or knives. A few of my friends have had to deal with knives, though, so maybe I've just been lucky. Anyway, back to my original point... I think that bouncing can be tough for a martial artist, in that you have to have the temperament to always keep in mind the interests of your employer, as well as protecting yourself and the bar patrons. Sure, the profession does attract the type who see it as an excuse to "whoop a little ***," but in reality, you really need to keep your head in some pretty intense and fast-changing situations. Opinions?
