I never ever leave my credit card with anyone at any gas station. While most people are trustworthy it takes only one dishonest person to record your numbers and the three digit security number off the back. It happened to us once, and that was one times too many. We will leave a driver's licence OR I will stand at the cash desk as a "hostage" while DH fills the truck.
Our credit cards worked everywhere in Alaska except for one pay-at-the-pump at Cantwell, and it turned out no one's card was working that morning. Good reason to always have enough cash in your wallet to pay for a fill-up.
