That's a strange analogy, ck. If you paint a picture of such a slow-filling gas pump, the audience will envision themselves holding a nozzle for hours at a time, wasting their lives away. I much prefer Cottonwood's (and others') approach which refers only to the time the owner spends on the mechanics of re-charging: about 10-15 seconds to plug in, and a similar amount to un-plug.

Back to the (in-driveway, NOT in-garage!!!!) pump - where I grew up, the mansion that The Rich Lady on our street owned was also so endowed, and her driver (NOT her chauffeur - that is a gauche term!) would let me do the task when I was old enough. Now, in Alaska, we're 160 miles r/t from the nearest station, so we have some half-dozen tanks around our compound (250- to 1,000-gallons) filled with diesel #1, #2, heating oil, gasoline.... it's not good to forget which is which.....
