I don't think it's limited to SysAdmins. I have a lot of users who rather give me a call and ask my how to center their text in Word instead of looking at the Word Online Help. There seems to be an aversion to using online helps and/or manuals. I also have the impression that people in general are not good at reading manuals (VCRs would be an example). I always take at least a cursory glace at a manual even if I believe to know the equipment.

Anyway, 80% drive-through and 20% sit-down questions is pretty good, I think.
