I was working with a German transport company at a time when England was playing Germany at football, and everyone was gathered in the canteen to watch the game. As always England lost at the football. I had a 6'7" ish drunk German shout in my face that "ve has beaten you at your national sport", I turned away retorting that "we have beaten you at yours, twice!" I was escorted off-site for my own safety and was transferred back to Blighty the next day.
