It's illegal to pump your own gas in Oregon and New Jersey. I traveled to Oregon and just started pumping my own and the worker there looked at me like I had 2 heads, so now I know. Independent stations typically are not self serve, but the big chains typically are (Exxon, Shell, etc.) I've been going to the independents since you can save a lot by paying cash, and these days it's actually nice to talk to people instead of listening to robot checkout voices.
