We leave the car running. Costco demands you cut it off.
The engine is at one end and the fill at the other. Smoking and filling a no no.
Cellphones not generally a problem but I've seen long sparks from just dry air, plastic shoes and starting to touch around the filler cap or door or other parts, of the car.
Usually there is no problem but touch the car with the other hand and insert the nozzle, maybe. One time I felt the charge build up and travel up leg then body and down arm finger then bang. I had no idea that static charge would build that slwoly, such as a second or so.
Wife didn't like it won old plastic seat covers. You could count on a charge just about every type movement then slowly approach her with the finger and zap.
