I actually had one guy who was so obsessed with the proper handling of his comics that he wouldn't let any other staff members but myself and the manager touch his comics. He was horribly rude to my coworkers if they tried to help him and would demand my help even if I was busy with something else. I'll always remember one day, the total look of horror on his face when he came in to find me, my boss and another coworker all hunched over a bucket of KFC, our hands glistening. He was obsessive to the point of scary. In spite of your sweet "kind" comment, Paul, I have to tell everyone that one day he ordered the official, full sized Zena Warrior Princess costume, which was over $300 if memory serves, and that I told my boss that this guy was probably going to tie his mother up and force her to wear it. He was such a mean, mentally off kilter guy that my boss was really bothered by the possibility of my suggestion.
Also, with all the guys obsessed with the slightest crinkle or fold, storing them in their acid-free-backing-boarded, mylar bags, in boxes that were guaranteed to be UV safe, the one customer who I truly loved, was a guy who religiously read Superman. He'd come in, buy his comics, roll/scrunch them up tightly into a tube-like roll, and just jam them into his over-stuffed back pack. It was so counter to everything else I saw that it was punk rock... almost erotic.
I'm actually giggling to myself right now, remembering all the naughty ways I posed our many action figures. Let's just say Mr. T was a pitcher, and Batman was a catcher, and Snow White was involved in a very not-for-Disney way. One day the figures were all gone, the rumour was that my boss thought I'd gone too far, but her never said anything, then a long time later, I found them all packed up in a box in the back room.
Like I said, I've got so many stories from that place that I could write a book. Maybe I should.
Also, Ash is right, for some of them, I could tell by the look in their eyes. *shudder*
