Why Waiting in Line is Torture
Perhaps the biggest influence on our feelings about lines, though, has to do with our perception of fairness. When it comes to lines, the universally acknowledged standard is first come first served: any deviation is, to most, a mark of iniquity and can lead to violent queue rage. Last month a man was stabbed at a Maryland post office by a fellow customer who mistakenly thought he’d cut in line. Professor Larson calls these unwelcome intrusions “slips” and “skips.”
The demand for fairness extends beyond mere self-interest. Like any social system, lines are governed by an implicit set of norms that transcend the individual. A study of fans in line for U2 tickets found that people are just as upset by slips and skips that occur behind them, and thus don’t lengthen their wait, as they are by those in front of them.
Surveys show that many people will wait twice as long for fast food, provided the establishment uses a first-come-first-served, single-queue ordering system as opposed to a multi-queue setup. Anyone who’s ever had to choose a line at a grocery store knows how unfair multiple queues can seem; invariably, you wind up kicking yourself for not choosing the line next to you moving twice as fast.
But there’s a curious cognitive asymmetry at work here. While losing to the line at our left drives us to despair, winning the race against the one to our right does little to lift our spirits. Indeed, in a system of multiple queues, customers almost always fixate on the line they’re losing to and rarely the one they’re beating.
