[Lee Stewart]

This phrase can mean a few different things. Hospitals can use it to signal a serious threat or mass casualties. If a store cashier issues a Code 10 authorization request while you’re checking out, it means that she’s suspicious of you or your card. She’ll call your credit card company and answer a series of yes/no questions to evaluate the situation and call the authorities if need be. If you’re in a Walmart, however, Code 10 just means there’s a dry spill.
