This is sort of a smartazz question but it's really a valid one. I was roadtripping through gorgeous Oregon several years ago. I got rude surprise late one night, just as I drove into Pendleton via Spokane, in that I wasn't allowed to pump my own gas; because of some Oregon State law I was told.
So, firesuit on ... If ya do not pump your own gas, and ya don't routinely hop back & forth across the river, how the heck can a driver know when the pump's not filling/working as expected ? BTW, We spent the entire following day enjoying Pendleton; that leather aroma of Hamley's saddlery. Then we followed the river to the sea.
