The advantages of breaking off a relationship at a highway rest/food stop are almost too numerous to list. For one thing, thanks to passing traffic no one can hear you if you choose to make a scene. Then there's the transient nature of the other customers, who are more interested in a bathroom break and a quick burger than they are in your love life. The restrooms themselves provide safe refuge, whether it's to wash your face (if you're sad), scrawl some graffiti (if you're mad), or triumphantly groom yourself for your next, er, victim (if you're glad). And of course the metaphor of breaking up next to a highway can't be ignored: Love, like traffic, may stall. But you will always, eventually, move on.
