Walkie-Talkie Carhops Speed Service (Dec, 1955)
The young lady in the photo (left) uses the lightweight walkie-talkie to call orders into the kitchen at Schilling’s Drive-in Restaurant near Covington, Ky. The woman in the car thus gets her food faster. It’s part of an electronic setup developed by Frank Lindley of Cincinnati. An operator at a reciever takes down orders fromt he walkie-talkie carhops. Then, when the food and check are ready, the carhops are alerted by different-colored lights on signal boxes located so that they can be seen from anywhere in the parking lot.
