One thing that annoys me (if only it were) is the way people, and it's always them ahead of me in line, don't pull out their wallets until they're rung up. I always admired folks who prepared their supermarket checks down to the amount, and sighed when they didn't—like they didn't see the giant sign outside and have to ask who they make it out to—or even stuck around to make their balance entries. Stupid lady at Fuddruckers waits for the exact figure before beginning the excavation into her monstrous bag. I'm certain she wasn't keeping up with the register. Are they afraid of being overcharged if they display too much money? A mugger or beggar hiding within our ranks? A contract-voiding last-minute myocardial infarction? Or maybe it's a gamble they'll be relieved the chore by being announced as the 1,000,000th customer and getting the meal on the house?
