Kitty - "one of the most beautiful and talented demi-mondaines of the eighteenth century" - moved in such wealthy circles that she could command the extraordinary sum of 100 guineas a night. The Duke of York, after spending a night with Kitty, gave her a mere fifty-pound note, since it was all he had with him. She promptly dismissed him and refused to receive him again. To further show her contempt, she sent the banknote to a pastry chef with instructions that it be baked into a tart and served up for breakfast.
