Fact
I usually get old people calling me telling me everyone they know uses a Mac and most of the world does, and thus we should tech support their computers. It's annoying. We have like 3 customers on Macs, out of thousands. If I'm not getting paid to train on a Mac, I'm not going to bother.
Also, people that call me asking for help but don't care to learn anything about their computers. Not even the basics of the computer or the internet. They just want a magic box that makes their pictures move and bitch at me when I tell them it's not our fault their 'picture box' is black.
