Checking out at a big box store yesterday, my purchases rang up at $16.04.
I handed the clerk a twenty, and he punched the payment into the register. Then he got a worried look on his face.
After maybe a three second pause, he reaches for the register next to his, and starts punching in data.
A look of relief comes to his face.
He then disbursed my $3.98 in change.
As I walked out of the store, my receipt supported of my suspicion.
The cashier had accidentally punched in my payment as $16.04 rather than a twenty, and he apparently had no idea how to figure how much I was due back without resorting to electronic intervention.
