I've seen the future and this is it.
You enter through the doors and boom, you're right in front of your clerk who is now an iPad. Being one who's not a huge fan of humanity I found this to be a very welcome development. The app walks you through all of your doughnut options in a clear and easy to understand manner. After you order you pay with a swipe of your card and you're done.
They make your doughnuts right then and there so they are nice and warm when they call your name. This makes all the world of a difference. Just YUM. I'm glad I don't live nearby because I'd soon be the size of a small whale.
