Heh, "coke" is the only one that sounds normal to me (I'm from the southwest). Where I'm from, if you ask for a coke at a drive-through, they'll ask "what kind?". And then you say "Sprite", or whatever you want.
Then you just say "Coke" again. If you sound confused, we know you're not from here. If you treat this as a perfectly normal and sane interaction, then you're one of us ;)
