I worked for a grocery store as a cashier during a semester of college...

One day, we got a warning about people going around trying to short-change cashiers by asking to break and combine things rapidly in hopes of getting more money than they'd handed over.

Somebody tried it on me, but I happen to be really good at computation in my head, so I had no problem with it...and when it became apparent what he was doing, I ended up shorting him some money. :P
