Check your change. I'm always suspicious with this that it's a varient of the "handful of wet change" scam.

By confusing you and diverting your attention away from the amount (forcing you to pocket the change quickly to dry your hands or juggle the paperwork), there's an opportunity to short-change you slightly, which mounds up if you're doing it to every 10th person...

When I were a lad, you used to get change counted out into your hand. Always a nice surprise when that happens now.
