It requires an average of4 minutes (exponentially distributed) to take and fill an order. The restaurant chain has a servicegoal of an average waiting time of 3 minutes. If the restaurant is not meeting its service goal, it can add a second drive-through window that will reduce the service time per customer to 2.5 minutes.
