I feel I can contribute here. I know what you are feeling in some small way, so I will share this story with you.
I was working as a (computer) lab monitor for the dorms while I was in college. Mostly helping people print stuff and the like. There was this girl who came in asking about some particular software she needed on her *home* computer. Normally we aren't supposed to help people with their home computer problems, but we weren't busy, and a friend of mine was there (he was a coworker as well), so we thought we'd be nice. She kept saying how dumb with computers she was, and we kept telling her that asking for help is not dumb at all, especially when you don't know. After about 45 minutes of instructions on how to install Adobe Reader from the CD she had for a class (it took a few tries to get through to her), she went on her way.
A couple days later, I get called by the boss (who is as computer illiterate as they come) to explain why this girl went and filed a complaint against me for calling her dumb. I told him the story, and that I had a coworker there who would back it up. He said "I don't care who you say was there," and tried to make me apologize to the girl. I said that I would not apologize for her *thinking* I called her dumb when I didn't, and now, I really do think she's dumb. He tried replacing me, but, since noone wants to work that crappy a job, he kept me on.
