" That sandwich man I’d replaced had little chance of getting his job back. I went bellowing up and down those train aisles. I sold sandwiches, coffee, candy, cake, and ice cream as fast as the railroad’s commissary department could supply them. It didn’t take me a week to learn that all you had to do was give white people a show and they’d buy anything you offered them. It was like popping your shoeshine rag. The dining car waiters and Pullman porters knew it too, and they faked their Uncle Tomming to get bigger tips. We were in that world of Negroes who are both servants and psychologists, aware that white people are so obsessed with their own importance that they will pay liberally, even dearly, for the impression of being catered to and entertained.
