Presumably NJ will required a professional to plug electric cars into the power sockets? Oh and come back a few hours later and unplug the cable?
In the UK self-service really started in the late 70s and became universal by the mid-80s. But it didn’t follow that you could pump your own unless someone was on-site to monitor all the pumps. That’s still the rule today in the UK.
In France - and just recently Spain, totally unmanned stations now exist and operate continuously. They are generally 20cents cheaper per litre than manned stations.
