Back in the mid-1990s. . . .
. . .I had the misfortune of working at the Pentagon's Helldesk for the Air Force.
And I actually got a "cupholder" call: a 3-star (fighter pilot, of course) had called in to report that his "cupholder" had cracked.
Yep. He was using the CD-ROM tray for his coffee cup.
I get there, diagnose the problem ("What, you can't glue it back together ?? How about replacing the tray ?"), call it in to order a new CD drive. Mind you, at the time, a CD Drive was a several hundred dollar piece of gear. And I mark it down as Customer Misuse of Equipment, which meant he PERSONALLY got the bill for parts and labor, about 400 bucks.
General blows a gasket, demands I retract the report. General ALSO had signed a waiver for training on the box, accepting, under his signature, personal liability to all damage to the computer beyond normal wear and tear. Never got to the end of the matter, as I left for a better job shortly thereafter. . .
