"some places" are full serve just about anywhere. The point of the post is that some local or state governments prohibit self-service.

I don't know what the initial justification was, but I did learn that it is beneficial to some drivers.

I went to college in NJ and had a friend in a wheelchair who had a car. He certainly appreciated that all gas stations were full-serve.

Did you transfer plates from a previous vehicle? Maybe the rule holds for newly-issued plates.
