Arby's tried this sort of ordering system back in the 90's. They had a touch screen CRTs at the point of sale. Customers placed orders by choosing from an on-screen menu. The system was setup to where an Arby's employee stood behind the machine, waiting for you to finish the order. There was no communication with this employee and so it made for quite an awkward experience. The system only lasted for a few months and they went back to taking orders using traditional methods.
