Insulting At A Collegiate Level

(I work in a bookstore during college. A classmate of mine also works there, and is cleaning the glass windows by the entrance. A father with a young son walks up and stops near my classmate.)

Father: *talking to his son* “See this, [Son]? That is why you go to college.”

Classmate: “Excuse me. I’m in college. This job helps me pay for it.”

Father: “Yeah? Well, I bet it’s not a good college.”
