A BMW driver at a gas station was confused when he spotted two different prices for the same grade of fuel.

Is the unidentified Shell gas station ripping customers off—or is there another, reasonable explanation?

TikTok user @shotsdenn documented the discrepancy in a recent clip that has thousands of views as of this writing.

“Check this out,” he says, turning the camera toward two neighboring pumps.

Premium fuel with a minimum 93-octane rating was listed at $5.16 per gallon on one pump. On the pump beside it, the same grade appeared to cost $5.76—a difference of 60 cents per gallon.
