"Thus a simple question would resolve it: Do you mean ..."
Indeed, I often think IT support people are needlessly arrogant (or themselves a bit clueless) about users' ignorance. So they can be dumb clucks, and they often use incorrect terminology, but I guarantee there are fields *you* don't know about so give them a break. If you aren't patient and don't have people skills you shouldn't be in support.
Which is not to say some users shouldn't be allowed to touch computers. There are some irredeemably thick people out there, and it sometimes feels like I've met all of them... until, that is, I read these columns in El Reg.
