I think they typically do it the way most people do. They just go to the gas station. I have seen commercial fleet gas stations that don't serve the general public. There's one Flyers/CFN station that I drive past on occasion as well as others. These are the most spartan looking gas stations I've ever seen - even more so than Costco. Maybe a booth for the attendant, and if it rains there's no cover. Also - I don't think they're required to have air and water like retail gas stations.
