Diagrams of two self-service gasoline stations, both located on corners, are shown in Figure (a) and (b). Both have two rows of four pumps and a booth at which an attendant receives payment for the gasoline. At neither station is it necessary for the customer to pay in advance. The exits and entrances are marked on the diagrams. Analyze the flows of cars and people through each station.

a. Which station has the more efficient flows from the standpoint of the customer?
b. Which station is likely to lose more potential customers who cannot gain access to the pumps because another car is headed in the other direction?
c. At which station can a customer pay without getting out of thecar?
