Interesting things happen when you work next door to a cash-for-gold place.
Today, some dude came in a dropped the remains of a decayed human-fucking-tooth (with gold cap) on my counter.
We politely pointed out he was in the wrong space, then I cleaned the hell out of my counter.
This is what comes of teaching our children about the tooth fairy - when they get old, they expect to be able to sell their used body parts to just anyone!
