To your comment about "rules restricting people who have little regard for the well-being of others", I have nothing to say but shame on you. Smoking is a choice via that person. You cannot tell who is a smoker from just looking at them (unless affected greatly by smoking), just as you cannot tell who is a thief from just another customer at a store. Just because they smoke, doesn't mean that they are out to get people who do not. I have friends who smoke, who are very nice people, yet I do not smoke myself. Don't make judgements upon a group of people based on stereotypes.
