I spend a goodly amount of time on the phone at work, and I'd say that it's more of a 10% rude factor for me. Instead, I tend to get confused people or people who automatically assume I have the ability to read their mind [which isn't bad really, just confusing]. This is also understandable - I work at a hospital, and people are seldom at their best when calling.

But the truly sad thing? 8 out of 10 of the rude people I deal with are *also* people who work at St. Mungo's.
