A and P what attitudes cause Mr Lengel to be angry with the girls?

Mr. Lengel's anger towards the girls in "A&P" stems from his belief in societal norms and expectations regarding appropriate behavior. He perceives their choice to wear bathing suits in the store as disrespectful and inappropriate, reflecting his conservative views on modesty and decorum. Additionally, he feels a sense of responsibility as the manager to uphold these standards, leading him to confront the girls rather than accept their nonconformity. This clash of attitudes highlights the generational divide and differing values between Mr. Lengel and the younger characters.
