An American tourist in London decides to skip his tour group and explore the city on his own.
He wanders around and eventually stops at a pub to try a pint or two of English beer. He continues sight-seeing and after a while, finds himself in a very high class area. Large stately residences... no pubs, no shops, no restaurants, and worst of all... NO PUBLIC TOILETS.
He desperately needs to go, after all those pints of beer. He sees a narrow side street with high walls surrounding an adjacent buildings, and decides to use the wall to solve his problem.
As he is unzipping, he is tapped on the shoulder by a London bobby who says, "You can't do that here sir!"
"I'm very sorry officer," replies the American, "but I really HAVE TO GO, and I just can't find a public toilet."
"Ah," said the bobby, "just follow me!" He leads him into the back alley, then along a wall to a gate, which he opens.
"In there," points the bobby, "Whiz away sir, anywhere you want."
The fellow enters and finds himself in the most beautiful garden he has ever seen. Manicured lawns, fountains, sculptured hedges, and huge beds of gorgeous flowers, all in perfect bloom.
Since he has the cop's blessing, he unburdens himself and is greatly relieved.
As he goes back through the gate, he says to the bobby, "That was really decent of you. Is that what you call 'British Hospitality?'"
"No sir", replied the bobby, "It's what we call the French Embassy."
