(A customer places an unopened box on the counter.)

Customer: “Can you please check to make sure this isn’t broken?”

Me: “Sure thing!”

(I open box, remove Styrofoam, check product, replace in Styrofoam, close box.)

Customer: “Excellent. I’ll take that. Actually, can I please have one that hasn’t been opened?”
