If they actually fired someone because they are a smoker they would get sued and lose in wrongful termination suit. It is the whole state, not just SF that banned smoking. I don't smoke, but think this is an undue infringement on civil liberties. Where the hell is the ACLU on this one? If a business is family owned and operated, they can allow smoking. It is amazing how packed the places are that allow it. I remember when SF banned it in bars, i thought it was ridiculous then, and still do. Yeah, this state is pretty messed up in a lot of ways.
