Is the latter a real concern for fast food outlets? That image shows an interface which is available in multiple languages, which frees up the humans in the establishment to serve the incoming orders more efficiently. In my experiences with those automated screens, there is still the option to go to the counter and order from a human if you really wanted to.

Is this universally a good thing? I don't know. It certainly reduces the role of employees to just process orders as fast as possible, where before there may have been a moderation on order flow by virtue of having to wait in line to speak to a human.
