I have been a non-smoker for some years now after several failed attempts to give up. I drink too but that is for a different argument. My wife is a smoker. I object quite strongly to all this non-smoking hypersensitivity. If you are a non-smoker a little smoke may be less than pleasant at over-close quarters. But it is nothing to the discomfort you impose on the smoker when you object to him or her smoking. Been there, done that. Please take your moral homilies and stick them somewhere else.
