Me: “Here you go, ma’am. That will be $26.50.”

Customer: “Wait just a minute. That isn’t my stereo.”

Me: “Actually, it is your stereo. The serial number is right here and it matches.”

Customer: “This isn’t the stereo I brought in to be fixed. It looks all different. What did you do to it?”

Me: “We cleaned it.”

Customer: “Oh…ah…thanks!”
