Fizzy drinks are perfectly functional in fountains. And dirt cheap for the restaurants, to the degree that the soda companies restrict their availability to consumers. The single use drinks are sold at massive profit. I joke that restaurants are almost universally places that break even on food, if they are lucky, and make all their profit on hard/soft drinks.
