True story, though I may not have the exact quotes (it was a long time ago)
While providing phone support for WinXP
ME: So when did this issue start Customer: It's been a while, and I've been able to work around the issue by shaking the computer a little bit now and then. But it's getting alot worse now. Me: So how often do you have to shake the computer to make the problem go away? Customer: Oh, once or twice a day. Me: I think you need to take the computer in to a local technician Customer: Really? I didn't think it was that serious.
