YSK if your company has a dedicated IT team, make sure you're someone's favorite person to help.
Why YSK: They get shit on by end users for a living and the people they're helping act like their problem is the biggest and most important problem in the world. Some of them actually believe it.
Be an asshole once, you're quickly forgotten. Do it consistently, you'll earn a reputation for someone that nobody wants to help. Be their favorite and most will go to great lengths to help you out if they can.
You won't get preferential treatment every time but basic human decency goes a lot farther than most people think. For the same reason, be nice to every cashier you meet. They deal with a lot more BS than you can probably imagine. #education
