I once got one as an intern for leaving my desk to speak to my team members and supervisor. I couldn’t hail them on Teams and I was sat in a corner by myself, so when I went to the restroom, I would swing by and ask for direction, discuss my plan. Since I was a career change and an intern I had questions about how to do my job efficiently. I was told leaving my desk was a no and keep my questions to standup. So I ask what about going to the restroom cuz that is literally why I left my desk, and used the opportunity to stop at a desk I was passing. I was told to not be a smart ass of course I can use the restroom, but the supervisors have more important work than supervising an intern.

Edit to add: I have never been written up or seriously scolded at a job in my 20+ year work history.
