Drive through call centers?

From Marginal revolution comes this story about a McDonald’s drive-thru in Missouri that relays its orders through a call center in Colorado, and then uses computers to present the order to the staff. The system has cut order time by 30 seconds, reduced errors by 50 percent and saved on labor.

Though Alex is surprised that it works, it just follows the same process as any other call center. Present one clear and consistent face and service to the user, minimize errors, and repeat it over and over.
