I was about to dismiss it as nonsense until he said the bag has a velcro system! A velcro system, imagine that.
Of course, cheap curmudgeon that I am, I used to just push the rubber boot back enough to trip the safety so the gas would pump. That way, I could see how much was in the tank and stop pumping when it was full. Now that I live in the United States instead of the Republik uff Galifornia, I don't have to deal with that crap.
