Y'know, one of the best billboards I've ever seen was across I-95 from the Phillip Morris headquarters in Richmond. It read, "Even communists are allowed to smoke."
For me, its more of a principle than anything else. Could I wait a few minutes or even an hour to have a cig? Sure. Should I have to? Not on your life! And don't even get me started on smoking restrictions outside. OUTSIDE!!!! Might as well get ready for the concentration camps...
