7. "I keep getting this weird error code. Can you fix it?"
This one wouldn't be so bad if it were followed by any actual information about the error code -- you know, such specifics as what the freakin' thing said, when it occurred, or what the user was doing in the moments before the issue arose. Inevitably, though, the user will have no recollection of anything other than the fact that an error message came up at some point during the day and/or night.
That reminds me: My car keeps making this weird noise. I'd better go tell my mechanic...
