This happened when I got my first IT support job. Naturally as a 1st line support you get to do the fun and not at all tedious thing of resetting passwords.

So I take a ticket from one of our HR people where they say that 3 new employees can't access a certain system.

Without going into too much detail here I reset the passwords according to our procedures and be done with it.

But at the end of the day it turns out that one of those 3 new employees was the new CEO, and he was known to be not the most pleasant of people to work with.

So ofc there was a chain of emails with the words "How can someone not know who I am" in there somewhere.

Had a nice stressful weekend wondering if I'll still have a job after Monday and we had a whole new password reset procedure created because of that.
