Many Oregonian's have either traveled, or lived in another state, so they've pumped gas before. The law had nothing to do with people's ability to pump gas. It was a wrong minded way of creating jobs.
All stations in New Jersey and Oregon in the United States offer only full service and "mini service". In these states, attendants are required to pump gasoline because customers are barred by statutes from doing it themselves. New Jersey banned self-service gasoline in 1949 after lobbying by service station owners and Oregon did the same in 1951. Proponents of the ban cite safety and jobs as reasons to keep the ban.
However, In Oregon a law passed by the Legislature in May 2017 and signed into law by Gov. Kate Brown in June will allow Oregon counties with 40,000 residents or less to deviate and allow for customers to pump their own fuel. The new law went to effect January 1, 2018.

It's nice to see New Jersey and Oregon are unwilling to change laws that were passed in the forties. Talk about progressive. I've lived in Oregon and I still don't understand it. Marijuana is legal, but pumping your own gas isn't.
