As to the long hoses, pick any lane, opposite side of the car. It is harder to pump the fuel in that manner. It takes more time, I have seen the long hoses just barely get around the back of huge SUVs like Infiniti QX80, BMW X7 etc, Land Cruisers, the nozzle sticks out, makes it hard for the attendant to get around the nozzle. Also makes it hard to pump the gas. Also makes it difficult to get the nozzle in the tank, most of the time. Cars is not that bad but similar.
The idea is for the convenience of the Costco customer, to just pull up to any pump, in any line.. does not factor in the different kinds of Costco customer, that don't want dirty fuel hose stretching across their back windshield, I don't think I have ever heard of one breaking but the tension would have me.. apprehensive, that's glass.
You simply cannot make everyone happy, all of the time.
