in Atlanta I would have to ask "what kind of coke do you have?"?!)
Well, I can't recall actually hearing that, here, but if it were asked, the server wouldn't blink an eye. Usually we say something like, "You want a coke?". If the answer is yes, the next question is, "What kind do you want?". Then the person says root beer, Pepsi, or whatever. I agree with my friend, who wrote me today that "The term "soda" was reserved for the fountain concoction of
> ice cream, flavored syrup and sparkling soda water." Though to be honest, I don't know where I'd go to get one, these days.
