I play a gig tomorrow night and the ventilation is not too good. The smoke is never terribly bad but bad enough. I know of a couple of people coming (then there's ME!), who really don't like the smoke. The bar is probably 60' x 60'. I was wondering if I placed a fan at the door (the only door that I know of), do you think that would help? If it blows along the ground, would that be about as good as up at the top of the door? Any ideas?

I was thinking of making a big sign for my stage "If you smoke, thank you for smoking LESS in here." I wonder if that would make smokers mad enough to leave. I don't want them to leave but I sure hate smoke and as I said, I know people who want to hear me but they hate smoke.
