Maybe I'm missing something, but why are you making/allowing the cashier (to) remove clothing from hangers? That's one of my prime pet peeves, folks who can't be bothered to take clothes off hangers and instead expect the cashier to do it, thus holding up the checkout line. I routinely see people with whole carts full of clothing, all with hangers still in place, just standing there watching while the clerk removes hangers. I've seen it take as long as five minutes. That may have been why she pulled the hanger off your tie without unclipping it--after eight hours of removing hangers, I can understand assembly-line thinking on the part of cashiers. A thrift store ain't freakin' Neiman Marcus. Neither cashiers nor anyone else who works in a thrift store can be expected to properly handle clothing.
Speaking of pet peeves, I thought of he-who-cannot-be named today when I encountered what appeared to be an abandoned cart in an aisle. It had exactly one shirt in it. I moved it out of my way and was going on about my business when I hear some a-hole say "Thank you." Paid no attention at first, then I heard him say "Thank you" again. And again. Finally, it dawned on me that he was talking to me. "Yes?" I asked. "Thank you for pushing my cart," he says. As if I'd pushed his little sister or something.
"Look," says I. "It ain't cool to block the aisle with a cart and go wandering. What are you, new?"
He was lucky I was in a good mood, having just scored a Willis and Geiger safari shirt. It was just sitting there, label open to the world, where he'd already been. Guess he really was new.
