Does a cookie count for dinner if it's the same amount of calories?

The more I'm trained on the job, the more I'm taking on. It's great, except that I'm not fast enough to be able to do things like, you know, eat. Today I had a whopping four minutes to sit down while waiting for the pastries to come out of the oven, so I grabbed what was ready in the store. We make this awesome chocolate cookie with dark and white chocolate chunks and macadamia nuts. I'm not usually a fan of chocolate cookies or white chocolate, but this sucker is gooood. And since it has about 400 calories, that's a meal, right?
