I used to work in an actual office where one of the meeting rooms had an en-suite full bathroom with a bath. It was a massive old building and at one stage this particular bit of it had been a flat for the caretaker. When it was turned back into meeting rooms, the bathroom was just left there.
I would entertain myself during dull meetings imaging how people would react if I just got up and said, ”don’t mind me, I’m just going to have a bath while we discuss this”
