If people are performing a legal activity that you do not approve of, go somewhere else. Besides, most restaurants have smoking and non-smoking sections.Sitting next to non-smokers AND THEIR CHILDREN in public places.
Sounds like an isolated incident.Waving cigarettes in people's faces. Heck, I nearly got HIT in the face by a cigarette from a smoker who was smoking in a prohibited place.
Your argument is absurdly emotional, it is as simple as that.Smokers are the scum of the earth. It is as simple as that.
