Self in restaurant on Long Island last year:
Waitress: "Where are you from?"
Me: "Oh, a small town near the Welsh border in central England."
Waitress "Wow. You sure speak English good."
Me: "Well, I'm English. I'm from England. It's my native language."
Waitress "Oh yeah I guess. You sure don't sound like an American. Is England near Wales, and is that the same as Scotland?"
Me: "Gosh, is that the time? I'd better go".
