Then your state almost certainly requires them to have extinguishers, or they have an automatically activating system. Not all states require an automatic system, but there is definitely fire specific equipment at the place where you are fueling your vehicle.

Familiarity with your surroundings is far more valuable than superstitious behavior.

In my state, there's no requirement for an automatic system, and no requirement for a fire extinguisher at the pumps, just that they have to have an approved 20BC extinguisher no more than 75 feet from the pumps.
