Abstract: The present invention extends to methods, systems, and computer program products for helping customers select lesser congested checkout lanes. A cashier can adjust a user-interface control to indicate customer congestion at his or her checkout lane. The indicated customer congestion is combined with indicated customer congestions for other checkout lanes (which may be more or less congested). The combined indicated customer congestions are used to form a lane congestion report for a physical store location. The lane congestion report can be sent to and presented at customer mobile devices at or near the physical store location. Customers can use the information presented in the lane congestion report to select a lesser congested checkout lane.
