The beginning of the story there are 3 girls walking up to A&P dressed in their bikinis. Even though they are 5 miles away from a beach in a small town. So they seemed to be dressed wrong
The girls got what they wanted at the story and are going to Sammy to pay for their items. Sammy is observing everything about them and is staring at them for their clothing.
As the girls are paying for their items Sammy boss Lengal walks out and yells at the girls for not having proper clothing. While Sammy is trying to defend them and Lengel doesn't like that
The girls leave the story and Sammy is mad that Lengel did that to the girls. so he proceeds to quit his job to get the girls' attentions. As he is leaving the store he regrets his decision to quit his job
After Sammy quits his job he walks out of the store only to realize that the girls have already left and he quit his job for nothing. Now he is thinking about what his parent will say to him
What do I do now
The literary term in A&P is Situational irony. Its Situational irony because what we least expect to happen happens. We expect for Sammy to say something to the girls but instead he quits his job and doesn't say anything to the girls.
