Sooooo ... you set this guy up on a piece of software that he's new to, and you immediately leave for vacation. While you're gone, he stumbles across a software behavior that he's not familiar with, and it makes him think he has lost everything. Apparently, you didn't show him how to access the backup, or where to find it. For two weeks he can't get anyone from IT to address the problem (for IT, trivial; for him, critical). And somehow he's the idiot?
