A support representative friend of mine came up to me one day and said that he thought he had done something wrong. He had been walking a novice Mac user through rebuilding her desktop. She tiresomely questioned every direction the technician made. After half an hour of patiently talking her through what should have been a one minute process, she finally stated, "Oh! Now it says, 'Are you sure you want to rebuild the desktop on the disk XXX?'"
Tech Support: "Ok--"
Customer: "Oh, now there's something like a spinning barber pole on the screen."
Tech Support: "You didn't press 'OK' did you?"
Customer: "Yes. You said 'OK'."
Tech Support: (acting alarmed) "I just said 'Ok,' I didn't mean for you to press 'OK'!"
Customer: (panicking) "What should I do now?"
Tech Support: "Run! Get out of there! Run! Run!"
The next thing he heard was the phone hitting the floor, the sound of rapidly retreating footsteps, and a door slam. After numerous calls over the course of an hour, the customer finally answered the phone. She had waited outside for an hour -- when the computer didn't explode, she went back inside and unplugged it.
