Kleptomania runs deep, apparently. It really violates the whole idea of a pipe show, which is based on common interest and a community of people. Retailers have to figure it into their overhead. I'm always irked when pipe shops put pipes under glass, but I understand the problem. It makes me much less likely to buy. I don't want to be meditating over a pipe while a staff person drums their fingers. It takes me an hour to decide. But that's the price we all pay for the personality disorders of the few. Childrearing requires careful and repeated explanations of ownership in a child's formative years, and enough gifts so a kid doesn't spend the rest of their lives trying to steal the gifts they never got, and some people are incurable. Always deeply disturbing to have ones stuff taken.
