i'm of two minds on this subject, on the one hand, it sucks to have to pay for stuff like that, but on the other, having to glad handle dozens or perhaps hundreds of people you don't know, some of whom can exhibit very creepy tendencies, and with the prevalence of people who want selfies, which is an even more intimate form of contact with those you don't know, i kind of can't blame them for getting something out of it.
