I’ve heard more than a few people ask me this, instead of “How are you?”… must be a lazy person’s way of not having to move their mouths too much. Sounds ridiculous, but then again, I find myself saying “'tsup?” or falling back on “howyoodooin?” in my old NY accent - both easier on the jaw.
Ahyahll makin’ funna hah-eye tahk when ahm tahd? Because it’s a burden to NOT do it at work. What’s especially difficult is to, when given the name of who I should contact, repeat it back in Yankee, not local, since receptionist will still hear it rhotic, as I’m a Yankee. Unless I’ve already code-switched into Piedmont, in which case I leave the note, “You have an accent,” pointedly not “Y’all gotta accent,” appropriate to the region. But I still have to type the name in Yankee.
In New Orleans, it used to be “Yat?” (Where are you at, in your present condition?) I think the New Orleans accent even became known as "speaking Yat).
Here where I live now in Texas, it’s “Doon?” (How are you doing?)
