point is, gas pumps have little warning stickers on them that say you shouldn't re-enter your car during the refueling process, because static might build up and ignite the gasoline. it seems to me that the best way to combat this would be to erect a brass sphere between each two pumps that people are required to place their hands on after exiting their vehicle. this sphere would be grounded, and might have a pleasing design etched around its circumference.

while at first people might be hesitant to utilize this for fear of shocks, over time this reaction can be quelled through the use of a system of capacitance sensors in the sphere that tell the pump to give you a discount over the marked price of fuel.
