Not too many years ago, cigarette smoke cost me an amp. It was a fan-cooled Peavey 600-Watt stereo amp/mixer that really rocked. The cooling fans, unfortunately, drew air through small vents and one end and expelled the air out the other. After two years of playing at the Havre de Grace, MD American Legion (Blood & Guts Saloon) cigarette tars had coated every slider, pot and jack connection to the point where they no longer made contact. Fortunately, I had an extended warranty and Peavey replaced it. I stopped playing there the following week. The smoke was so bad that a pair of $3,500 smoke eaters had no effect on the air quality at all.

As for the sign, it would probably result in instant unemployment.
