You are the Best Customer

A businessman told his customer, "Thank you, Mr. Smith, for your patronage. I wish I had twenty customers just like you."

"Gosh, it's nice to hear that, Mr. Paul. But I am surprised," admitted Smith.

"Usually I'm the one who argues with you on every bill and then ends up paying late."

"No, I would still like to have twenty customers like you. My problem is: I have two hundred!"
