The One

Me: Anything else?

Customer: No.

Me: Great. Have a good one!

Customer: What is it with you Charleston people. That is offensive, but I like it.

Me: I'm sorry.

Customer: You overuse "one" One can be anything. I could go home and eat a sandwich. I could eat one sandwich. Is that the "one" you mean?!?!

Me: I meant day.

Customer: (She walks away in a huff) Really! You southerners are sooo weird.

Me: Have a good DAY!
