At the grocery store, I had an order that totaled $7.15.

Gave the cashier a $20 bill, and 15 cents.

Suddenly there's muttering, so I look at the screen; she's punched in $2.15 tendered...$5 still due.

She's trying to figure out how to change the $2 to $20

So I tell her to just enter another $18 tendered. Oh. Hey...it worked!

This was not a new employee...
