This is something I saw at COMPUTEX 2017 that should work in the US people can adopt to this. In Japan and maybe in Taiwan, many fast-food stores have ordering kiosk where people place their order and pay. Then people proceed to pickup their orders. This eliminates human error when receiving orders. Also eliminate order taking personnel. Other benefit includes no cash handling by the people there for there is no need for theft.

I just do not know if people in the US are up to wording using kiosk (machine).
