How To Spot An American Tourist In London
1. You can always hear Americans long before you can see them, as they speak very loudly and very slowly.
2. They are usually so fat they take up 2 seats on the bus or on the tube.
3. You can spot them lurking outside McDonalds or Burger King, drooling as they contemplate having there 3rd burger of the day.
4. The camera dangling from their necks just shouts out look at me I'm an American.
5. The most ridiculous and my personal favourite the good old fanny pack, only an American would have one. WTF would anyone want to wear one of those things.
6. This one is so bad that I can barely bring myself to type it, sandals with socks, usually white ones.
7. They complain the main course in a restaurant is smaller than a starter back home.
8. Americans are always complaining about something, basically because things are different from back home. Well I have the answer stay at home!
9. Many Yanks love to wear brand new stand out a mile white trainers, as well as ugly sweatshirts.
10. You can usually spot them wandering around beside London Bridge, trying to figure out why it is so ugly and not like the pictures. When in fact they are looking for Tower Bridge.
11. Americans get tired after walking for longer that 20 minutes because they are so use to driving everywhere.
12. Somebody needs to tell old American guys that wearing a baseball caps over a certain age, make you look kinda weird.

1. Americans are loud. Talk less loudly. Many Europeans speak English very well. There is no need to speak extra slowly and there is certainly no need to increase your volume. If you meet someone who does not speak English, speaking loudly will not help them to suddenly do so. Americans also talk very loudly with each other. I know that might be harder to avoid, but observe other people around you and speak at the same level. It's not a contest—you don't need to be louder than them.
2. Americans complain because things are different from home. Well, you do. Ok, not all of you. Many are open-minded and want to experience difference. Why the rest of you bother to leave home, I don't know. A couple of things Americans usually complain about:
Caffeine. Most Europeans do NOT drink decaf coffee. So don't ask for it. Even if a restaurant or café claims it has decaf, they don't. You won't know the difference until it's too late.
Smoke. Most European restaurants do NOT have a non-smoking section. So quit whining about the smoke. You are not going to get lung cancer from a two-week vacation. Besides, if you are travelling during high tourist season, you probably won't have a problem finding a smoke free (or at least a less smoky) restaurant because they'll all be filled with other American tourists. My advice: Suck it up!
3. Ugly white tennis shoes. I see this all the time. American tourists are soooo easy to spot because they wear brand spanking new blinding white sneakers. I know where this comes from—it's from all the suburbanites reading tour books warning them to "wear comfortable walking shoes." Americans, who drive their cars everywhere, generally put up with uncomfortable shoes more than others. So how to buy comfy shoes is a mystery to them. They go to their local sports store or nearest LL Bean catalog and purchase special shoes just for the trip. If you don't own comfy shoes that you can walk miles in, they please buy some! But don't get white sneakers. Try Birkenstocks, Doc Martins, or some other shoes that don't look like they were meant for exercise.
4. Funny hats. Baseball is an American sport. Baseball caps are distinctive American head wear. Nothing screams "I'm an Ugly American Tourist" like a baseball cap—ok, the white sneakers are worse. If you are worried about getting sun in your eyes then wear sunglasses.
5. Fat Fanny. I bet some guide book told you that a "fanny pack" would be a good idea. It would keep your hands free and deter pickpockets, right? Whatever. Seriously, would you wear one of those silly fanny packs at home? To work? To school? Then why on your trip? Backpacks are fine—get a small one. For women, use a purse! The same one you use at home should be fine. Yes, yes, I know "Beware of pickpockets." And you should. But wearing a fanny pack is ASKING a pickpocket to come get you. Do you know why? Because ONLY American tourists wear them! Don't be afraid to use your normal purse or school backpack (but please, please, pleeeeeease don't wear the backpack on your front). Simply be aware of it at all times and wear purses bandoleer style.
6. T-shirts, sweatshirts, and blue jeans. A trip to Europe is not a weekend driving in the country—even if you are spending the weekend driving in the countryside. Europeans, generally, don't dress as sloppily as Americans. Think "business casual" all the times. When in doubt, wear all black. You'll be mistaken for a British tourist. If you cannot afford a new all black wardrobe, then purchase a Canadian flag patch to sew onto your backpack. (But if you sew it onto your fanny pack, everyone will know you're an American trying to be Canadian).
Here is another excellent article about cultural misunderstandings when touring a foreign country. I won't jam it down everyone's throat by re-posting it here but very interesting read.

And finally, I apologize to anyone who do not act this way but is lumped in anyway through stereotyping.
So in conclusion.....I'm sure there is one here but I'm too lazy to make a point.
