I don't know, GfS. It depends on what you really want to do with your time today, I guess. I think you're akin to a musician playing to an almost empty arena here. You look about and there are five, maybe six people scattered about in the stands. One is asleep. Another pair are talking loudly and laughing. Another is yelling "WHOOOO!" every now and then and swigging his beer, but he doesn't really know why. And Jack is over in the corner spraying "cock and balls" on the walls with his spray can.

You have to ask yourself whether merely practicing your craft is justification enough for carrying on with the gig regardless of the largely oblivious public, just to hone your skills. It's your call.
