(I work at a sandwich shop across the street from a high school. I serve a lot of teachers who come over here for lunch.)

Me: “You want a turkey on white with tomato? That’s [price].”

Customer #1: “Oh, and can I have a bottle of water?”

Me: “‘Course!”

Customer #1: *scoffs* “I can’t believe you just said that. As an English teacher, I think I should tell you that saying that isn’t proper English.”

Me: *not sure what to say* “Um… sorry?”

Customer #1: “There you go again! Those are fragments, not complete sentences! All the other teachers who come in here would be ashamed.”

(The customer behind her speaks up.)

Customer #2: “Yeah, well, I’m a math teacher, and trust me, we don’t care.”
