Somebody tell me if I am wrongheaded in my thinking. With the price of fuel as high as it is now and the heights we've seen in say the last fifteen years, we are seeing all kinds of "fuel card" operators spring up. Open Roads, greelane, and mudflap just to name a few. There was a time when owner/operator truck drivers would leave the house with a pocket full of cash to pay their bills. Then comes along comcheck which would work for owner operators or company drivers. More and more cash being handled as fuel prices crept or shot up. More potential for leakage at the register. The truck stop chains got more spread out and concentrated into corporate conglomerates. The fuel/discount card comes along and does away with cash. A smaller chance for leakage at the register. The fuel cards, I suspect, are backed by venture capital groups or some other cash flush entity. Pilot or any other high volume fuel handler sells the fuel card company the fuel for basically a handling fee and small margin. The fuel handler makes a 5-10% margin on the fuel. Maybe less, I don't know. The fuel handler then proceeds to make money off of all the ancillary sales and services that accompanies the fuel stop. The card service pays the fuel handler the next day and decides what they want to charge the consumer to maintain the margin they want to maintain. they charge the consumer the next day and make their percentage. Rinse and repeat. Not so much with us RVers, but trucks are probably refueling every day they are operating. This is probably not exactly how it works, but I suspect it is some variation similar to this. The poor sap that doesn't a fuel card gets pillaged until he figures the "scam" out. And now fuel is mostly cashless.
