I do support for stand-alone photo kiosks. This story revolves around the PC/Windows 2K version. A friend of mine in the call center here thought he had taken the cake with one call of his. He was trying to walk a customer through running the recovery CD to reload the OS. She told him that her mouse wasn't working. He of course checked the connections and such. It turns out she had the mouse held backwards...in the air and was moving it back and forth in front of the monitor.
We had a good laugh at that but I stunned him into silence a week later when I related the details of a very similar call. Again, we were trying to run the recovery CD. Her mouse wasn't moving for some reason. Remembering the situation I found hilarious a week ago, I attempted to describe the mouse after we verified it was plugged in to make sure she knew what a mouse was. I told her it should be generally rectangular, 4 inches by about 2 1/2 wide. It will have 2 buttons on the top of it. She seemed to understand but after a little more troubleshooting to no avail, I knew something was wrong. The problem floored me when she casually described the mouse as being black. "black?" I said. "It should be a grey plastic. Can you describe this 'mouse' to me?" She proceeded to describe to my horror the small USB speaker that normally sits next to the computer. And guess what else? She was holding it in midair, waving it back and front in front of the monitor.
