…he is unlike the other customers. They sense it too, and look at him with hard eyes, eyes like little metal studs pinned into the white faces of young men [...] In the hush his entrance creates, the excessive courtesy the weary woman behind the counter shows him amplifies his strangeness. He orders coffee quietly and studies the rim of the cup to steady the sliding in his stomach. He had thought, he had read, that from shore to shore all America was the same. He wonders, Is it just these people I’m outside or is it all America?
