If someone sits besides, and you don't like the way he looks or smells or whatever, you get up and move away....and these days where the hell can you be, that a smoker can sit next to you? Bar? Hell no! Library? Hell no! Store? Hell no! Office cubicle? Hell no! The anti-smoking assholes have banned cigs pretty much everywhere, and are working feverishly on banning it in apartment buildings here (so one cannot even smoke in one's own damn apartment).
