This is not my original but from a very experienced retired cabin crew member:-
I'm trying hard to imagine on a busy flight, wearing a jumpsuit and needing a tiddle .... unbutton and remove top, part of which manages to soak up some of the scum from the soggy sink area, before lowering it to drop the trousers, the bottoms which by now are absorbing the urine spills .... and whoops .... bit of unexpected turbulence causes a bit of a dribble over the crumpled outfit ...... Can't possibly come out of loo looking like that ........ Welcome to ''The Worlds Best Airline'', ''Well Take More Care of You'' ........ AND ...... wearing our fancy new outfits!!! SPEEDBIRD ...... come in SPEEDBIRD ........
