I'm not concerned about shade for those whose toxic fumes I have to inhale. They can suffer lol. Some of you were very put off with my earlier thoughts, and that is understood. It is a bit extreme. I think my problem with smokers has to do with the fact their activity impacts me more than any other vice. From having to inhale the smoke, to the littering with each butt. If smokers were considerate: 1) smoked where allowed, 2) tried to keep their smoke contained from non-smokers 3) AND this is a big one... properly disposed of their butts... it would be an entirely different story from me. I can only imagine the count of butts left on the ground from the entrance to the parking lot. Instead I'm left with the impression that most, not all, are lazy, inconsiderate, and for starting the habit in the first place I view them as weak minded.
