Last week a I purchased a burger at Burger King for $1.58.
I gave the girl $2 and 8 cents.
She just stood there, holding the nickel and 3 pennies,
while looking at the screen on her register. I sensed her
discomfort and told her to just give me two quarters, but she called
the manager for help. While he tried to explain the transaction to her,
she started crying.
