> Here in the UK (we don't call it gas, so that threw me off, and) not 'pumping your own' is unheard of - payment either self serve at the pump (in the last ~15y anyway, since 'chip & PIN' I suppose), or inside.

This is also true almost everywhere in the US. Except that we do call it gas. (The word is not directly related to "gas", the phase of matter; it's short for "gasoline", which appears to have originated as a brand name.)

The fact that pumping your own is legal everywhere without any problems doesn't prevent people in Oregon from forecasting dire calamities if the law of Oregon were to change.
