Customer relations

Had a young guy as a customer today wearing an Oregon State University t-shirt. I said to him, "I believe, if I'm not mistaken, that the Oregon Country Fair is in the next week or two?"

He replied, "Really? Are they going to put it in this parking lot?"

I said, "The Oregon Country Fair?"

He said, "I know that they have a fair in this lot once in a while."

"That they do! But I think the Oregon Country Fair is probably held in Oregon."

He looked at me, paused, considered the wisdom of my reasoning, then stared into the air above me scratching his chin. "Oh, yea, I can see that."

"You borrowed that shirt, didn't you?"

"Yea, how did you know?"

"Lucky guess. Have a good night!"
