The story is about a teenaged boy named Sammy who works at the local A&P grocery store. One day he encountes a trio of swimsuited girls in the grocery store. The girls cause quite a stir because of the way their dressed (or not dressed.) The girls come to his checkout station, and one girl pulls a dollar from her bathing-suit top. The store's manager, Lengel, spots the girls and reprimands them for their attire. The girls are embarrassed and want to leave quickly. Sammy, in a passionate moment, tells Lengel that he quits. The girls, however, fail to notice his act of chivalry and continue walking out of the store. As he, punches "No Sale" on the cash register, he realizes that the world will be a harder place for him from now on. The story has remained popular because many of the themes are still central to adolescence, including accepting the repercussions of one's choices.
