I work at a university, in a computer / electrical engineering dept., and I run across this level of dumbassery daily. You'd expect Ph.D.'s who work in the field to be smarter than that, but no. It helps to remember that it's not your job to teach them how to fix their problems, it's your job to fix it for them. If they don't want to learn the easy way, they can be inconvenienced by the hard way.

I had one of these jagoffs (with an MSEE and an ECE PE) tell me all the computers in their lab were broken and they wouldn't do anything - turns out they forgot the login password, which is "password". And, I'm not the IT / computers guy, I'm the electronics tech (instruments, components, test rigs, etc.). 10 to 1 says I'll do it again - for the same person.

The upshot is - you can and will deal with these people all your life. Don't take it personal when they're willfully ignorant and self-important. That's just job security. You ever tried telemarketing? If you have, you learn the true meaning of "I can't deal with these people much longer".
