Confused To The Nines

Me: *answering phone* “Hello, thank you for calling [Store]. This is [My Name]. How can I help you?”

Customer: *clearly a young teenage guy* “Uh…yeah, I was just wondering what time you are open until today.”

(Note, it is currently 9:30 am.)

Me: “We are open until nine today.”

Customer: “Nine in the morning or, like, nine?”

Someone In The Background: “Dude! Did you seriously just ask that?”

Me: *stifling laughter* “Nine at night, sir.”

Customer: “Oh, okay…”

Me: “Was there anything else I can help you with?”

Customer: “No… no… that’s all.”
