Londoners, They're just like US.

1. They run into people they know on the Tube.
2. Crazy people preach on the street.
3. They go to yoga classes. And arrive late.
4. They talk about transportation (though not as much as us).
5. They rush through the tube stations, almost knocking people over.
   
6. They drink Starbucks.

Not so much like US:

1. They don't complain all of the time.
2. Taxi Drivers are friendly and don't talk on their cell phones.
3. They are slower in general. Actually, everything here is slower.
   
4. Tipping is rare at bars, added at restaurants (usually) at 12%, and only for good service in taxis.
5. They take buses over the tube when possible.
6. They buy things is small packages and not at Costco (not that there is anything wrong with Costco. Has anyone seen the last episode of Modern Family? You should watch it). On that note, everything here is smaller. It is Europe, after all.
   

I'm sure I will keep adding to this one!
