I think kiosk the reason is they aren't using kiosks for now , is that they will accurately keep metrics and some people in today's day an age still don't have smart phones. Especially kids that might walk to mcdonalds on their way to and from school. Eventually they will have the apps and drones but these kiosks will pay for themselves within a few a few months. And there is a learning curb as some other restaraunts had these things 8 years ago and people were intimidated by the machine to not look dumb since they didn't know how to use it
