Sammy's sexual attraction to the queen is also shown in this passage, "with the straps pushed off, there was nothing between the top of the suit and top of the head except just her, this clean bare plane of the top of her chest down from the shoulder bones like a dented sheet of metal tilted in the light." The story also demonstrates a teen's disdain for authority figures, usually older people, and their penchant for going against the rules and not conforming to the norms. Sammy's disdain for authority can be gleaned from the way he described a shopper, "She's one of these cash-register-watchers, a witch about fifty with rouge on her cheekbones and no eyebrows… if she'd been born at the right time they would have burned her over in Salem" ("A&P by John Updike").

For Sammy, pride appears to be more important than his need, "Sammy, you don't want to do this to your Mom and Dad," he tells me. it's true, I don't. But it seems to me that once you begin a gesture it's fatal not to go through with it" ("A&P by John Updike").
