Computer repair shops / fixed my computer for free after I spilled beer on it, and also retrieved all my data [full disclosure: deep-seated personal gripe]

Ah, I've been in that job. My favorite in the stupid-expectations department was a customer who expected us to lie about the cause of a failure on the work order, so that his insurance company would cover the repair. When we refused, he made his own edits to his copy of the work order....and a few days later brought the machine back (I forget why) and handed us the edited order.

We photocopied it (without telling him) and filed it with our own copy. That was entertaining when the insurance company called.
