Years ago, Chick-Fil-A had larger sizes of their milkshakes. Now they only have a small one. As a kid, I'd always get the bigger sized one as that was the perfect size if you wanted a lot of milkshake, like the same amount Steak N Shake offers- but now they are all a uniform small, tiny size. They are over $6 for a kid size shake.

I have shakes on rare occasions, not all the time, so when I want one, I don't want a tiny serving. Old school milkshakes, like the previously mentioned ones at Steak N Shake, are a decent size.
