Wawa (a chain of convenience stores that is pretty big in the mid-Atlantic region but non-existent elsewhere) has, of course, self serve soda fountains. At these fountains, you can get a little squirt of some special flavoring, like chocolate or cherry, in your soda. I went to get a Coke Zero today and decided to try this. Big mistake. I didn't get much; maybe 2 tablespoons of chocolate syrup stuff in a 32 ounce soda, but it was awful. It ruined the drink. I could handle about 10 ounces of that concoction before I dumped the rest on the ground.
