Well, given the choice, I go in armored. My suit's fairly distinctive, most people know by now not to start something with me, and most of those who don't have warrants out. If that's not an option for some reason, I'll prepare the ground--either create a distraction or get two factions of patrons poised to go off at each other. Then it's simply a matter of using the chaos for cover and controlling the rate of engagement through maneuvering. Almost textbook.
