The entrance to the nearby BART stop is crowded with a dozen homeless people, so many that it’s actually hard to get down the stairs. None of them bothers asking me for money, because, as I’ve been fascinated to discover, my McDonald’s uniform is like an invisibility cloak when it comes to panhandlers. The whole time I work here, exactly one guy hits me up while I’m in uniform—and I don’t really count him, because his “Hey, spare a cheeseburger?” was clearly meant to make me laugh.
