Me: *ringing up a sale* “…and did you find everything you were looking for today?”

Customer: “No.”

Me: “Oh, that’s too bad. Would you like some assistance finding those items?”

Customer: “Yes.”

Me: “Okay. What was it that you couldn’t find?”

Customer: “No.”

Me: “…pardon?”

Customer: “Yes.”

Me: “So…did you not need any help today?”

Customer: “No.”

Me: “Then you have everything you need?”

Customer: “Yes.”

Me: “Well then, have a wonderful day!”

Customer: “No.” *takes bag and leaves*
