What no one has broached here is how to CYA on future automagic gas purchases.

Do these pumps issue a printed receipt?

Is there some test you can run to be sure it's stopped charging you? (Such
as trying to pump again, and getting prompted for the CCard?)

Can you get your credit card programmed to have a transaction dollar limit?
