Self service gas is still illegal here in NJ. I believe we are now the only state in the union where this is the case. I'm reminded of this every time I'm driving out of state and I stop for gas. I invariably sit in the car at the pump for a few seconds, waiting for the attendant, before I go, "oh, right..." and get out of the car!
IIRC, also illegal to pump your own gas in Oregon.
