The Shock And Thaw Strategy

Customer: “I need a fan.”

Me: “What kind of fan?”

Customer: “A fan for where I plug my modem in.”

Me: “Do you have it with you?”

Customer: “Yeah.”

(Customer leaves and returns with the computer. A hairdryer is duct-taped to the power supply, nozzle pointing into where the fan normally sits.)

Me: *dumbfounded* “Why is there a hairdryer taped to your computer?”

Customer: “Well, I have to keep it warm, or it will freeze up.”
