No, smokers think that if there's no visible smoke, then there's no longer even the potential of any health threat to the next guest. You see, when the "studies" decrying the health threat of second hand smoke were thoroughly debunked, the anti-smoking crusade had to quietly adopt the "we just don't like the smell" line. Hoosierskypilot has somewhat more adroitly adopted the dual "it's for the children/it keeps my taxes high" gambit. Both are lacking, in my opinion. Which one do you subscribe to?
