American English uses get a bit more than British English, although young people here ( my daughter for example) have started using it instead of have. e.g. 'Can I get...?' when ordering in a restaurant rather than 'May I have...?'

Oh yes - the become/get thing!
I always cringe at customers e.g. in a bakery when they order - not: "May/Can I have/get... - but: "I get a bread." As the seller, I would tell them: "No, you won't get a bread unless I'm so kind as to give it to you..."
Btw, there's the famous German/English exchange between "get" and "become". The German verb "bekommen" means "get" and the English "become" means "get" in German.
("Waiter - may I become a beefsteak?" - "If you wish...")
