I've done IT support a fair amount in the past. People who do it exaggerate how bad it is, but it definitely will bring out any latent misanthropy you have.
One takeaway lesson everyone should learn, though, is don't fuck with IT people when they have some script they're literally forced to go through with every caller. Just pretend to do that shit you already did like turning it on and off, or actually do it.
There are two possibilities. One is that the person you're talking to actually is an entry-level moron who can't fix your problem. In that case, you're best served by getting through the shit that kicks you up a tier. The other is they're actually smarter than their pay grade, and this is not all that uncommon. In that case, you're also best served by getting through the dumb script so they can actually fix your shit.
The misanthropy of IT people comes from the fact that the vast majority of people are morons who think that somehow yelling at some guy a thousand miles away will fix a broken piece of hardware, or fix their own stupidity.
