I get gas at a very busy Costco regularly and even though the lines look bad they're actually very efficient, because Costco 1) has longer gas hoses allowing you to reach both sides of the car 2) has a middle lane allowing cars to enter / exit the gas pump even when there's someone in front of them. So even with ~50 cars waiting the average wait time is only like 5 minutes
