Personally, if I were trying to discourage people from smoking, my sign would be a little different. In fact, I might even go too far in the opposite direction. My sign would say something like, "Smoke if you wish. But if you do, be prepared for the following series of events: First, we will confiscate your cigarette and extinguish it somewhere on the surface of your skin. We will then run you nicotine-stained fingers through a paper shredder and throw them into the street, where wild dogs will swallow them and then regurgitate them into the sewers, so that infected rats can further soil them before they're flushed out to sea with the rest of the city's filth. After such time, we will sysematically seek out your friends and loved one and destroy their lives." Wouldn't you like to see a sign like that?
