It actually was much later in NJ, as the oil companies had them pass a law against self service. I had people with NJ tags on their car sit at the pumps and blow their horns. They would either drive off mad or come in the store, I'd really make them mad, and they'd still drive. I'd tell them it's self service. Pump it yourself. If you can't, then go up the street to a full service station and pay a lot more.
