What are the major conflicts in the plot, and when and where do turning points occur?

Sammy is a nineteen-year-old cashier at the A & P, a large supermarket chain. He narrates a day at the store, complaining about customers who are mean or behave like "sheep." He is critical of the commercialism of modern culture. Three beautiful young women enter the supermarket wearing only their bikinis. Many of the shoppers are shocked by the women's skimpy attire, but Sammy and his fellow cashier are enthralled. When the girls check out, Sammy's manager Lengel tries to lecture them about their attire. This is the turning point of the story. Sammy is outraged and quits his job, hoping to impress the women - but they have already left. He wistfully regrets leaving his job, and thinks to himself that life will be very hard from now on.
