it's a hack in the Bruce Schneier "easiest way to steal pancakes has nothing to do with where money changes hands" sense...
Our goal is to eat, without paying, at the local restaurant. And we've got a lot of options. We can eat and run. We can pay with a fake credit card, a fake check, or counterfiet cash. We can persuade another patron to leave the restraunt without eating and eat his food. We can impersonate (or actually become) a cook, a waiter, a manage, or the restraunt owner (who might actually be someone that few workers have ever met). We could snatch a plate off someone's table before he eats it, or from under the heat lamps before the waiter could get to it. We can wait at the dumpster for the busboy to throw away the leftovers. We can pull the fire alarm and sneak in after everyone evacuates. We can even try to persuade the manager that we're some kind of celebrity who deserves a free breakfast, or maybe we can find a gullible patron and tal her into paying for our food. We could mug someone, nowhere near the restraunt, and buy the pancakes. We could forge a coupon for free pancakes. And there's always the time-honored tradition of pulling a gun and shouting, "Give me all your pancakes".
