(I was working at a Subway about a year ago)

Me: “Hi. What can I get for you?”

Customer: “Let me see.” *looks at the menu* “A sub.”

Me: “What kind of sub do you want, ma’am?”

Customer: “I want provolone cheese?”

Me: “What kind of meat would you like?”

Customer: “Excuse me?”

Me: “What kind of meat?”

Customer: *agitated* “Are you being rude?”

*storms out and stands in front of the store for a few minutes telling people not to come in because of a rude employee*
