there's lacking technical knowledge, which is fair enough (unless you're an IT manager, and I've dealt with more than a few IT managers that know less than I did when I was at school, 20 years ago)
and then there's sheer fuckwitted dumbass retards that don't have the brains that the gods gave a left handed screwdriver.
There's phoning me up because you don't realise that clicking the "cancel" button will cancel the operation that you want to cancel
There's threatening to sue us because your email wasn't delivered because you'd tried to send it to homail.com
There's spending ten minutes arguing, swearing to almighty jeebus that there is no address bar in you internet explorer and then suddenly realising that it does
there's me asking "are you using windows XP or vista", you saying "XP" and then after me tearing my hair out wondering what's happened to your control panel, you saying "Oh, this is actually and apple mac"

I know I'm not perfect but I do a fair job of hiding my ignorance
