Also, LH, doing the water damage themselves makes it possible for them to declare the service contract void and not do any service on the computer at all, even though we paid extra for the extended service contract.
The other thing that just makes it all so obvious was the fact that the manager wouldn't sign anything guaranteeing that the computer is in at least as good condition now as it was when we brought it in. If they didn't do any damage to the computer, he shouldn't have any problem with signing something saying that they didn't do any damage to the computer.
