My "favorite" is: the total comes to $1.77 and I give them $2.02, for

they even try to calculate the change. I tell them I did that
intentionally because I don't want a lot of loose change back. Then they
look amazed when they run it through a their computer and realize they
only have to give me a quarter back. (Although some party poopers then
give me back dimes and nickels!).

...or give them the two cents after they've punched the $2 into the
computer. They're totally stumped.

Catch a clerk going off shift when she counts the coins in the till.

Verbally, I chime 94, 95, 96 ....

They have to start over because I broke their concentration BTDT.
