In the last few years, I’ve heard my daughter saying in restaurants things like: Can I get the pasta? That usage of get still sounds very odd to me. If I said that, I would mean: Can I bring the pasta to you? not Can I receive the pasta from you? Intending the latter meaning, I would say: Can I have the pasta? (Actually, I would probably say: Could I have the pasta? But that’s a story for another day.)
There’s obviously a change in progress here. In fact, my wife now says it too, but my dinosaur ears haven’t got me there yet.
It’s American usage.
