"Perhaps it makes sense that a citizenry accustomed to strange odors, and inured to foul ones, would detect a sweet one (or one, at least, that they associate with sweetness) and call the authorities. But the fear, such as it was, seemed to give way to a feeling of good fortune, as though we’d been visited by invisible aliens from a planet where breakfast is served twenty-four hours a day—a place, in fact, not unlike this one."
