It's 100% true. My uncle owns a fairly large gas/service station. The profit from gas sales effectively paid the rent for the service station. He paid all of his employees (and himself) with money coming from the car repair business. The gas pumps were irrelevant to his own profit, but required a lot of hassle/wasted time.

About 2 or 3 years ago he bought a larger building, hired more mechanics, and didn't build gas pumps. They're just not worth the hassle.

For perspective, the credit card companies made more money per gallon than he did as the gas station owner.
