First: take a couple who want to pay for their burgers by debit card.

Get the couple to give their order: 2 Whopper Jr's and two Rodeo cheeseburgers, say.

Cashier: "That'll be $4.33, sir."

Customer: "Okie dokie. Here's my debit card."

Cashier: "Thank you sir."

Cashier types in $4.33.

Cashier types in $4.33 again.

$4,334.33 is charged to the debit card.

Something similar to this happened last week in Palmdale California, at a Burger King, as reported by the Associated Press.

The couple got a full refund for what was an accident on the burger chain's part, and the couple didn't have to pay the original $4.33.
