Suferboy, of course I have. When it's quiet and I'm desperate, in the cruise and only when I implicitly trust the F/O. I am allowed by my company to do this.
Would you rather have me sitting there only concentrating on not peeing my pants? Have you heard of distractors? Probably not.
I would not however, leave the flight deck to shout and scream and stamp my feet, probably distracting the F/O from his job, whenever anybody wound me up a little bit. That would be dangerous.
Leave your emotions at home.
Now go away.
