There's no winning with Americans... I was in Knightsbridge tube station the other day, and I took a call on my mobile before boarding the train; it just so happened that I was standing near the underground map, whence I saw an American couple, quite old, with baseball cap, back pack and all. I decided to be a good representative for my country, and tried to help them out; so I said to them: "Where are you trying to get to?" "Holland" At this point, I thought to myself, forget it... Better not to ask them how they intend to get to Holland from Knightsbridge underground station, as they may find it rude. However, I think they read the subconscious, bewildered expression on my face, so the man continued, "Holland Park" "Ah, well you ought to take the Piccadilly line east to Holborn and then take a Central Line back west to Holland Park" "But it looks much closer if we change at Green Park and Bond Street" At this point I gave up, and walked off... I really did not want to get into a discussion about how the Tube map is not to scale or geographically accurate. Not only that, but they would also spend longer waiting for trains. Surely, they would realise that a man with a local accent, in a suit is not going to direct them wrongly, particularly given they were in T-Shirts and Shorts... Hear Hear! Really? I love misdirecting European tourists; it's great sport. Must be an American thing . . .
