Anything I need to know about the speaking culture in the UK, please?

What do you mean by 'the speaking culture'?
That doesn't make sense.

They have different sayings. Like any foreign place, they have different things in their daily life than we do, and so you'll see less references to things you're familiar with, and more references to things you're not. There's not a McDonalds in the U.K to my knowledge, and even if there were they'd probably serve lamb on their burgers. There's also a lot of tea over there, but people still drink beer there.

Seems like you're not too good at written communication either.
