Some years ago, when I'd recently acquired a Commercial glider rating (ah, don't you just love the USA), it was decided for me that a good wind-up for certain club bores, beloved of their flying overalls, would be the sight of me in flying overall, complete with my bars from the day job (merchant navy). Joe Public's reaction as I was introduced 'this is ChampChamp and she'll be your instructor today' was amusing...but, better still..
...... it had the desired effect.
