The McDonald's down my street got robbed the other day. Some guy went up to the teenage boy working the cash register, said he had a gun, and demanded all the money in the drawer. The cashier remained calm, opened the drawer, and proceeded to meticulously count out all the money, taking his time to ensure he, the eyewitnesses, and the surveillance cameras got a good look at the thief. Then after the thief left, the cashier went right ahead and served the next customer in line while the manager called the police.
The thief was caught and arrested within a few hours and booked for armed robbery. That cool, collected cashier? My son.
