One that REALLY annoys me is customers in shops saying, "Can I get...[etc]?"

Can you explain that to a foreigner?

I've been using "Can i get..." when ordering beer. Should I say
something else?

Historically "Can I get a beer" meant "Can I come to your side of the
counter and get the beer myself?" whereas "Can I have a beer" meant "Can
YOU get me a beer?"

But the usage has changed and "Can I get a beer" is now used commonly by
young English people, so you shouldn't worry about using it. It doesn't
make you sound foreign, it just makes you sound young.
