A system and method of queuing orders locates data-entry modules relative to a
pickup location such that a customer who places an order after a customer who placed
an earlier order can be signaled to approach a pickup location before the first
customer if the order of the second customer is ready before the order of the first
customer. The system can signal a customer to wait in a predefined location until
the order is ready, or the system can signal the customer to approach the pickup location.
