Which reminds me of the story of one of my Belfast colleagues who was walking down Lexington Avenue in New York one night. He didn't trust the hotel safe so he had the Queen's imprest in his pocket. A mugger came up behind him, stuck something hard into his back and said something witty like "Make with the bread, man".
He responded with "Don't be silly, I'm British and we don't have any bloody money"! He got away with it and our friend went off into the night to find someone else to mug. Colleague got into the nearest bar at a fast lightning pace and got on the outside of several double scotches. I don't think he was ever the same again.
