Some great stories of good cabin crew humour.
A c/s in our company when doing the safety PA likes to say to the pax regarding lifevests.
"There is a whistle with which to attract the attention of any passing sharks....."
However you'd be surprised at the amount of complaints we get about this sort of jovial behaviour.
My opinion is that a little bit of banter helps relieve what can very often be a stressfull situation for some people. However all it takes is one pax to have a sense of humour failure and the letters of complaint about "the attitude of your cabin crew in what is a responsible role ensuring the safety of the passengers....blah blah blah.."
I guess some people can take it, others can't.
