Sweet Drinks

With the exception of breakfast and dessert, the meals we eat usually are not sweet. Our drinks with them, however, are. We will eat a meal consisting of savory, buttery, salty and herb-like tastes, but we will choose sweet tea or coke to drink. However, when we eat breakfast and dessert, we might drink something unsweet like coffee or bland like milk. It just doesn't make sense to me why we choose those flavors to go together. You wouldn't put a scoop of ice cream on top of fried chicken, so why do we drink sweet tea to wash it down?
