One of the things I've found interesting about EHell is finding out little bits of information about America, such as your word for "grill" being "broil" and what you mean by "biscuits". It has seemed, in several threads, that other people might be interested in this too. So I thought I'd start a thread. If anyone has any questions to put to people across the pond from you (in either direction!) put them here, and hopefully someone from the relevant country will answer. Feel free to add more info to anyone else's answers, too, or give a different perspective.
A couple of my questions to start us off:
In the UK, class has very, very little to do with how much money one has. We have millionaires who are working class and penniless peers. I've heard that in America the opposite is true, which might have something to do with what else I've been told - that your ideas of class are less all-pervasive than in the UK, so the main thing to base assessment of someone's class on is how much money they have.
Your measurements in recipes are in cups - do you have a special sized measuring cup in the house or just use a random cup/mug of the right-ish size? Do you use kitchen scales for anything?
Is it the norm for Americans to introduce themselves by name to everyone they meet or is it just tourists here?
