And that people really do puke on you from time to time!
Funny you should say that but I was recently puked on by a FA, she was highly embarrassed and offered to wash my shirt, which would have been a little odd as I stood outside the toilet bare-chested while she was doing it!
And when I worked as supernumary crew many years ago and we flew snotty snooty beastly cheeky schoolkids to 'the colonies' I learnt that misbehaviour can be corrected very quickly at a prearranged signal to the captain to announce 'a little turbulence' and push the stick forward!
