I have a good friend who does this. He’s from Pittsburgh.

I have a coworker who does this, who is from Pittsburgh. (I’m in Cleveland).

On Whose Line Is It Anyway, Drew Carey always said “Go ahead and start whenever you hear the music.” That always annoyed me, and puzzled me too, because he’s from Cleveland, and that’s not a local usage.

Yeah, while this sounds completely normal to me, the examples quoted in the OP would have me looking at someone as if they just started babbling incoherently.
