I have posted this elesewhere but it's worth repeating:
I was flying dear old B. Cal from Gatwick to FFaM and sitting up the front. There were not many folk on board, so after serving us all an excellent hot breakfast, the stews congregated in the galley in front.
I was privileged to overhear this conversation......
"...and when I went there to the back row of seats, he had his willy out !"
"Och Fiona, whatever did you do ?"
"I said to him in a very stern voice: 'put that thing away, and I don't want to see it again until the end of the flight'"
There was a stunned silence, followed by giggles, and one very red-faced member of the CC departed the group, having realised all too late the implications of what she'd said.
