One of the times when Jan and I had made plans for after work, I arrived a bit too early so I decided to just watch Jan finish his work. He was working for a TV production company at the time, so this was quite interesting.
As I walked through the office, Jan’s boss noticed me and thought it was Jan. The boss started yelling at me very loudly because Jan’s task did not allow him to leave his post while they were doing live TV.
I just said, “relax, I’m up there working” and walked on.
The boss didn’t get it, of course.
