When passing through Oregon it's something I usually forget at the first stop for gas. Sometimes they are quite rude as I go for my usual self pumping routine. However my last time down there last year, they seemed more chill and made it sound more optional.
I do understand after 70+ years this will wipe out a whole level of lower skilled jobs for people that won't be easily replaced at a full level across the state.
Locally there's one municipality (county) that bans self serve but overall there is a little full serve but it's a higher paid option offered with self serve. Self serve is what most stations are.
