11. You buy an item for $1.27. You hand the clerk two dollars. Without a
using a calculator, how much change should you get back?

We've seen kids at a cash register practically in tears trying to make
change when the power went out.

I love it when the bill is $11.06, and I give them $21.11, so I can get back
a $10, and a nickel, and they can keep their ones. It takes them a moment
or five to enter $21.11 as Amt Tendered, then the amazed look at when it
flashes $10.05 as change, they look amazed or ask, "How did you do that?"

Priceless.
