Some of us play in venues where most of the audience are ok, or at least not a distraction for the ones who like us. It's just the odd dumb drunk or wild office party that is the problem. We learn to deal with it, if performing is what love to do, and it helps to let off steam a bit among friends at a forum like this.
It's not complaining it's bonding!!
Of course we'd rather play folk clubs and festivals when we can. Remarks like "well just don't do it" are meaningless to a performer. How could we just not do it?
Jerry Lewis said, "Open the fridge door, the light comes on, and I do a few routines" Now that I understand.
