The pumps have to be staffed in Oregon also....

@Skylane's claim isn't exactly false.  Per Google:

New Jersey is the only state in the U.S. that doesn’t allow customers to pump their own gas — anywhere. There’s always an attendant on duty to pump gas for customers at these full-service stations.

Oregon is the only other state besides New Jersey with a full-service law. However, Oregon’s laws are far less strict and allow certain parts of the state to have self-service gas stations.
