Seriously though, some of the descriptions of culture of drinking soda in this thread make me think of that movie. For last 15 years I had soda maybe 10 times and it was usually like few sips. I just can't phantom a world where soda is what you drink when you are a thirsty or to meals. I don't remember people I eat out with ordering soda to their meals either. It's usually water, tea, coffee, sometimes fruit juice.
I drink far more Coke Vanilla Zero than could possibly be good for someone when at home, and yet when eating out I generally get iced tea with no sweetener. You may know a closet soda addict and not even realize it. :)
