But remember no purchase occurred. My wife swiped the card and then cancelled the transaction. The nozzle never came off the pump.

Can’t say why, my guess its a pending transaction and when it’s not submitted will be gone
Remember the second the card was swiped all the information was given

[Clinging Bitterly]

It doesn't matter, the purchase transaction was activated and as it has already been said a hundred times, the actual sale amount would not be known for a while. The final sales go through later in batches by way of whatever mechanism the station's charge processing company uses.

A couple years ago we were driving back to NM from Oregon and I stopped at a station near Tonopah NV and just as I was starting to fill up all of the station's pumps quit. I got just a squirt of fuel if any. So I went to the next station down the road and filled up there. Later on we stopped at a Subway in Las Vegas to get lunch and my card was declined.

Now, it is good to have a small local bank. I called and talked to a human person and they got it fixed up lickety split. The two gas station stops within a short time frame triggered a hold for a possible stolen card because as far as the bank knew my card had been used to purchase two tanks of fuel at two different stations within ten minutes and within a mile of each other. Confirming my identity and that I was indeed at those two stations cleared it up and in fact they canceled the hold on money from the first station on my word that I received only a small amount of fuel there and the rest of the trip was fine.

(But for stubborn fog completely spoiling our side trip to the Grand Canyon.)
