Almost ever time I respond to a smoking thread I am sorry that I did (not you). They are convinced that it is all about control. The only thing I want to control is the air I breathe into my lungs. I will avoid smokers ever chance I get, not control them, AVOID them.
The bans on smoking in bars came about because the workers were exposed to second hand smoke. Instead of having your attitude and just working someplace else if they wanted to avoid smokers, the nannies just banned the rest of the population from smoking. If there were a big demand for non-smoking bars, that would have been a great business opportunity if the free market were allowed to operate.
