Obviously Not An Outsider

(My flower stand is outside right next to a payphone, which starts ringing.)

Me: “Hello?”

Customer: “Hi is this [Auto Company]?”

Me: “What?”

Customer: “[Auto Company]? I need someone to look at my car.”

Me: “Sorry, this is a payphone. I just picked it up because I heard it ringing.”

Customer: “Are you sure you’re not in [Auto Company]?”

Me: “Nope, I’m outside.”

Customer: “Can you check?”
