Someone pointed this out a few days ago, and it is pretty puzzling to see lines of cars six deep waiting for gas by Costco. The price is maybe 8 cents per gallon cheaper than neighboring gas stations with no lines. How in the world does it pay to wait that long to save under 2 bucks a fill up. Arent most of the Costco customers upper middle classs? Presumably they would value their time at way more than that- not to mention that there is gas wasted idling etc.. Or is there a different lower class clientele that is mostly utilizing the gas station?
