Huh, for me is the polar opposite. Maybe it's because I mumble, is unclear or don't speak the native language as well as the natives where I live, but I always preferred the kiosks. I seem to always get what I order then, and it's a lot easier to customize things. Generally just feels faster, which I guess is the most important thing about fast-food, I want to be in-and-out of there as quick as possible, the less humans I have to deal with, the better.
