A girl I used to know worked as an air stewardess for a well known British charter airline.
She felt a bit bloated one day, but carried on.
She was mid cabin serving drinks from the bar trolley and someone asked for a beer.
The beer cans were in the bottom drawer, so she bent down but accidentally squeezed out a fart as she did so.
She was suitably embarrassed, but hoped no one noticed.
Behind her she heard a little voice "Mum, she just farted in my face"
