I once had a black tie ball organiser ask me remove my miniatures, even though the invitation specifically stated "Black Tie - Decorations".
The chap who had insisted that the event (nursing graduation ball) be "Black Tie - Decorations" hadn't counted on anyone other than he and the (ex-QARANC) Head of the School of Nursing having dangling tin and it seems he had done it purely as a way to brown nose the boss. Why he was so keen to show he had a pulse when the Queen's Golden Jubilee happened is anyone's guess.
