Well one thing is for sure, I'd be fired if I acted like him. But, he does put across how it feels to be a tech sometimes.
Nothing quite like telling a user for the 10,000th time that their problem is because of all the adware they have on their system. It'd be so much fun to lay into these people.
Tech: "Your computer crashed again because you have too much adware on here."
User: "Huh, what's adware?"
Tech: "For the 10,000th time it's what happens when you go to shady websites and install their software. You're not supposed to be browsing for porn on your company's time anyhow. What's the matter not getting it at home so you're browsing chickswithdix.com on the company computer?"
User: "What?!? I'm calling your boss right now."
Tech: "Go right ahead. I'm sure your boss would love to see this list of websites you've been visiting while you're supposed to be working."
User: "You wouldn't dare!"
Tech: "Wanna bet loser?"
