Dr. No:A Novel by Percival Everett:
A better, more pressing question was how was I going to locate Eigen? I did the only thing I could think of. I wandered the halls calling out, “Eigen, Eigen,” like an idiot. Perhaps not even like, but as an idiot. Soon I was hopelessly, despairingly lost and puzzled all the more because none of the corridors led to anything that might have taken me out of the building. After coming to believe that I had covered the same hallways several times, never seeing a person or a color, I found myself standing in front of a vending machine. In it was nothing but bag after bag of barbecue potato chips. I had no change, no bills, no cards, as my clothes had no pockets. Though not hungry, I really wanted those chips, if only for the color. I shook the machine and startled myself with the noise and my own aggression. Then I shook it again, more vigorously, with equal success.
A door opened a couple of meters away.
