I'm blessed. I leave everything set up. I walk in, pull the tablecloth off my keyboard, plug in my power strip, turn on the kb and start playing. If I get thirsty I signal the bartender or waiter. When I finish I get a gourmet meal. People drink enough to think I'm good and they seldom BOO.
And on top of all that they PAY me pretty well to be there! Yes it's four hours, but no set-up time, no lifting and plugging and all that stuff. I don't make as much as pilots, but it ain't bad either, and I don't have to worry about the plane crashing.
