Thanks for all of the replies so far.
For those curious I am bouncing at a small bar in small town Maine that rides the line between dive bar and neighborhood bar/grille. I wouldn't take the job if the regular patrons were Mongols, Gangster Disciples or women from New Jersey.
That's not to say there aren't knuckleheads to deal with - there are - but the typical crowd is a mix of 20 to 40-something regulars who like to smoke weed, drink beer and dance like white people. Last week the whole bar was done up in blacklights and the band played songs like "I'm Shrooming", "Smoke Two Joints" and "Jump Around". Luckily nobody got shot.
I also work with a 350 pound partner on busy nights, and just about any given night there are more than a few guys who can and have stepped in to help handle someone getting violent with the staff. The cops stop by almost every night to say hi and everyone on staff has a very good relationship with them.
As for me, I don't consider myself much of a fighter, but I've came out on top in all recent engagements, none of which I instigated. At 6' tall and 290 pounds I'm a big boy with physics, brute force and sobriety on my side. I'm not invincible by any means, but I'm good with the odds knowing what I know about the type of trouble I may have to deal with.
My current thoughts on the gig are "I can't believe they pay me for this". Normal duties include people watching, high-fiving, shaking hands, getting hugged, getting felt up, slapping some asses and declining drink offers. I'm both single and eschewing all alcohol for the near future so this job is a great way for me to get out a bit and get laid. I've "cooled" a few tense situations but otherwise it has been a lot of fun.
There's always a certain level of risk, but that's true every day you get out of bed.
