These kiosks are already in tons of McDonald's locations from what I understand (I've only seen them in Canada but I'm told they're elsewhere) so I don't get the hesitation.

They work well, especially if there's a long line or you're hungover and don't want to talk to anybody.

What I'm wondering is when they're gonna figure out how to replace the cooks with machines (though that's a different task from kiosks, you need actual robotics) and staff the place with a single manager to deal with customer complaints.
