Yeah, it will take some time, but I guess eventually they will only have machines taking your order in fast food places. Maybe they'll have one person for multiple machines to make sure nobody has problems. Amazon has made stores now that literally have no cashiers. You just sign up in the app first. You scan your phone when you go in and there are sensors and cameras that detect what you take with you. You just walk out and Amazon automatically bills you for what you took. This is the future. Now they just need to automatically stock the shelves, I guess. Haha.
