Among those who attend shows I say absolutely not. This is still extremely rare. I also know of reports like this turning into a misunderstanding. Someone packs up their pipes, gets home and finds a pipe that doesn't belong to them, or the guy missing it finds it got stuffed into a different bag when he packed up.I'd bet if you put 100 pipe smokers together, the percentage of honest vs dishonest would be no different than in society as a whole.
