A.M.
it might not be you. sometimes i think they "disable" them. i think it was florida...somewhere i lived it was against the law to have the little lock thingies on there. i don't think we're supposed to get back in the car, regardless....that's when the static can build up. plus i always imagine knocking the pump out when i shut the door or something, and causing some giant disaster and being on the evening news lol.
now granted, i do use them when they have them available...it IS awful nice to put my hands in my pockets! :) but i also notice the gas pumps a LOT slower doing it the "automatic" way...so most of the time i get impatient and just hold it in so it goes faster....
