Dr. Pepper, a double agent! Who does he work with: Coke or Pepsi?

Dr. Pepper is originally a Pepsi product. I hate the fact that some places only serve Coke products and some only serve Pepsi. Maybe they are trying to get along. Pepsi sucks really bad. Dr. Pepper is my favorite fountain drink, but coke is the only choice for bottles or cans. I might have a Sprite occasionally.
