It's a pretty funny thread, and I would love to hear the song live. Next time I'm in the Bay Area, perhaps. Of course people who think they are not included in the rules, which in most public places are now also local custom- folkways- and flout them, and have a thumb in the eye or smoke in the face for those who ask for immediate observation of the rules- are in fact scum, regardless of which side of the Atlantic their definition comes from. They smoke where their children will breathe it, and likely do so all day. The only thing which enables real empathy in an agressive smoker for everyone else is quitting, for even a few days, because only then will they really understand that there has never been a small place with two people in it where only one was smoking. People who knowingly make other people smoke even after being asked not to are at least bullies, who would not do it if they thought they'd get a pop in the snoot for it. Sometimes the gentle song is not as satisfying as the really assertive one.
