People who think you're an idiot and try to describe every little step of something, but you've already figured it all out.
This happened with me when my mother called tech support because her printer wasn't working - she had somehow deleted the drivers, annoying as hell. "Yes, now to get to the Control Panel, click on the start menu and look on the right. Okay, now click on Printers..." all in a heavy Indian accent. I could've fixed it myself and spent the entire time hinting at the guy that I know what I'm doing and please go away.
