Nightclubs and taverns will be hardest hit and their patrons will defy the ban. In Appleton, WI, which also banned smoking, bars simply substituted ashtrays for cups of water for smokers to discreetly dispose of their cigarettes.
Folks, the security guards in the building I work in are actually in the underground parking garage (that has a huge ventilation system for clearing exhaust) taking pictures of smokers with Polariod cameras!
