you add milk to make it drinkable. Ice cream only shakes don't. Don't know what else to tell you. There are plenty of other places nationwide that make non drinkable shakes. Jack in the Box is one I have had that you would only drink if you had the suction power of a Dyson. Not as thick as JCW. Just one off the top of my head. Oh, and I like milkshakes better btw.
