UK and USA: A Comparison

So today I thought I would go through and list the things I have noticed that are different here in the UK. Watch out for part two, because I'm sure I'll discover more.

1. Nightlife. The drinking age over here is 18, and the students take full advantage of that fact. Binge drinking is not uncommon here, and sometimes people will go out every single night of the weekend. Clubs are a big thing in Manchester, and there are plenty of them to choose from. Sankeys, Fifth, the Factory, take your pick. Drinking is also completely allowed in accommodation halls, so many students will go out and buy alcohol, and then just get drunk in the common rooms. In fact, the Hall where I stay even has it's own in-house bar. It's very different from the United States, and it still makes me nervous, like someone is going to call the police on me.
2. Shopping. In the UK, the tax is already included in the marked price. So you always know exactly how much you'll be paying for any given thing. If the price tag says £5, you pay £5. Not £5 plus 7% sales tax. I think the U.S. should do it like that as well. I like it much better. No surprises. They also have this store called Primark, and I think it's my new favorite. 
3. Toilets. This one is a bit odd. Here in the UK, the toilets themselves are the same, but they don't hold as much water. Toilets in the United States have the bowl half full with water. But in the UK, the toilets have a couple inches of water and that's it. The first time I used one I thought it was broken. Also, don't ever ask where the bathroom is when out in public. They'll laugh. They call public restrooms toilets, as in "Where can I find the toilet, please?" 
4. Money. Everyone knows that they don't use the U.S. Dollar here in the UK. They use the Pound Sterling, which has that fancy "L" symbol to go with it; if you wanted to write fifty pounds, it would look like this: £50. There are pence and pounds, and just like in the U.S., 100 pence makes a pound. Whats weird is that each banknote looks completely different. A £20 note and a £10 note are different colors and different sizes, whereas the bills that we have are all pretty much uniform. Every coin and banknote also depicts the same person: Queen Elizabeth II (the current Queen). They don't have a different person for each coin and note like we do.
