My biggest irritation when I worked for IBM was management judging me on how I was performing my job when most of them didn't know how to do my job.Lol! Not so smart, just one of those people who has to see and feel it to believe it!
The owner of the company always gives me the hairy eye ball when he sees me coming in to the office with dirty hands.
I would not have it any other way, I refuse to ask my people to do something I would not do!
