Most of you lot will never ever fly business ir First on QA but just in case you ever do I strongly advise that you read QAs Guidleines for Farting for First and Business class Passengers.:
It is considered to be offensive to pass wind in First or Business Class so should the need arise First and business Class passengers are requested to walk slowly backwards into Economy and let rip when they reach there. I think that this is a wonderful policy which was given much thought by the Board of QA. Apparently they felt that Economy passengers stink in any case so the addition of the odd First or Business class fart wouldnt mmake much difference. Yippee, Yippeee, its Bombay gin for me!
