In the broader market, restaurants have been generally slow to adopt customer-facing technology for ordering and checkouts. Francie Mendelsohn, the president of Summit Research Associates, which studies self-service systems, said automated kiosk ordering at some restaurants is "logically a no-brainer, except practically it hasn't worked all that well."
Mendelsohn said the automated systems often have "build menus" and when customers start deviating from them the process can get time-consuming. Sometimes, customers may not get what they want.
"Of course, with a human there's a very good chance you're not going to end up with what you ordered, either," she said.
