I don't know of anyplace around here (or for 100's of miles around) that doesn't have a pre-pay policy. Every State I've visited has that picture of the State Patrol Officer / Actor picture on the pump "Steal Gas, Lose Your License" or whatever that State decided as their tagline.
With CCTV, that license number could be gathered and the resulting knock at the door of the Cops would ensue. Stations almost have to demand pre-pay these days (or they used to, before the engineered, pre-election price drop began
)
