smile - she could probably just tell by your voice that you were young and gorgeous
I was on a flight one day with a quite rowdy bunch of country passengers who were all keen to chat with me as I walked through the aisle doing comfort checks. One lady asked me to turn around and face my bum towards her ! I said " excuse me ? " ..anyway she motioned me again to spin around and the next thing I felt was a prod on my butt, of course as quick as a flash I spun back around to find her holding a piece of fluff which she had picked off the back of my uniform pants !
Also had a bunch of cheeky pax laughing at me one day as I was walking through the aisle handing out morning newspapers - little did I know that I had newspaper ink all over my face which had rubbed off from my hand - how embarassing.
