they seemed hot and ready to serve, a waiter came up and carried them all away. Moving backward, always backward. Darrel felt nauseated by the unnatural process. He got up and left the restaurant abruptly. Wide eyes followed his progress to the door. He moved with the crazy crowd that went back-side first. Ahead was a parkway that had normal, stationary benches. He would sit on one. He had been sitting on the bench, watching this incredible world of retropulsion a half hour when he caught sight of the girl in the yellow tunic.
