Outside of not fueling near an open flame, the more moderate strategy is to always plan your exits and know where that fire suppression button is relative to where you are.

My car doesn't have a "fire suppression button", nor does my gas station, the closest they have is an emergency fuel cutoff switch that stops the pumps, but it doesn't do any active fire suppression.

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.
