Moral Quandary

Today I went to get the one Peppermint Mocha I was allowing myself this season. It's one of my very favorite things about Christmas, but I fear it is also one of the things that puts on extra pounds. At the drive through, I ordered a tall (small), non-fat peppermint mocha with no whip cream. I pulled around and there was one car in front of me. I waited FOREVER to pull up for my mocha. I wondered what these people must be ordering! However, after about five minutes they were handed a single drink and drove away! I pulled up to the window and paid for my drink. I don't ever get a receipt and I know that it was $4 something. It's always $4 something for me at Starbucks. I had to wait another five minutes for my drink. While waiting I can see them making the drinks. The barista makes an iced drink - not mine. She makes something she puts whip cream upon - not mine. Then the window guy brings me the whip cream drink. After ten minutes, I'm not going to argue about a little whip cream. Really, I don't care that much. As I drive away, I notice that I don't have a tall(small) drink, I've got a grande(medium) drink. Should I have taken it back? A grande drink is also $4 something, so maybe I paid for the larger drink. I just wasn't paying that much attention. Maybe I ordered that grande drink? I think that I wanted a grande drink, but I was going with a tall drink because of the diet. They wouldn't have been able to sell the drink they gave me and would just have lost out making me a new drink. Plus, I'm not really truly sure I didn't pay for the grande drink. I drank it. It was delicious and I would do it over again, even with the extra calories.
