When I was a newbie FO on the Dash 8.....we had just landed (felt like we had been shot down, although, thankfully it was the captains leg) and the Captain had stood up - why, I dont know, as he had to face his audience disembarking - when a sweet looking little old lady (could have been your grandma) collared him and, in a very upper crust, loud and demanding voice asked of him..."Young man, was that your landing.....?". He nodded and she then said "....because it was fu**ing awful!!" In about as piercing a voice as you could imagine!! I was absolutely wetting myself in the flight deck....you wouldnt have thought that the little old lady could have possibly ever heard such language!!
