the other day my friend and I were at starbucks, and I asked my friend which frappuccino I should get, vanilla bean or double chocolate chip. she was kind of sidetracked at the time, so she replied, "get vanilla chip." I was like, "uh, that wasn't an option", and so we wondered if they do that; make mixed frappuccinos. neither one of us wanted to ask because we didn't want to get funny looks if the answer was no, but now I'm really curious. so, anyone got an answer?
