Soda, pop, cola, or coke?

While visiting my aunt in a little store she ran in Mississippi, she asked me if I wanted a "Coke." When I said yes, she asked me what kind I wanted, grape, strawberry, orange etc. I was excited as I had only heard of cherry Coke at the time. When I said "grape," she gave me a grape soda, not a grape Coke. So, what do you say soda, pop, cola etc, and where are you from?
