I don't think it's that dramatic, Sunfish. I think it's more that the f*cktards running AirBP don't want to or know how to arrange installation of bowsers which accept credit cards.
I reckon the biggest favour AirBP could do for GA in Australia is to pull their bowsers out of wherever they happen to be installed, so that sensible businesses can install some 21st century fuel-delivery technology of the kind that exists at every other location.
