And sometimes, when I'm in the mood, I really like to **** with them. The "Microsoft support" guy called once so I acted like a complete newbie (Oh no, this sounds serious). He told me to go to my computer and click on the little windows icon on the lower left of my screen. I kept telling him I can't find it, etc..etc.. and he spent a good 5 minutes trying to talk me through what to do to give access to my computer so he could "fix" it.
Finally, I said. "You keep saying for me to click on the windows thingy, but I don't see any windows. I only see Ubuntu." Click, he hung up.
What's unfortunate, is these guys, the "IRS" guys, etc.. DO scam a lot of people, especially older (than me) and more vulnerable ones. Very unfortunate.
