In MA, some towns ban self-serve, such as Milford. So local jurisdiction can apply, too.Like Imperial noted it was back in the '60's and early '70's. When unleaded fuel became mandatory, those pumps disappeared. Eventually full service went away as well, except in NJ and OR.
Some of them require all the cars to face the same way at the pumps, or the operator will shut off the pump on a vehicle facing the wrong way. The reasoning (faulty, I believe) is that they want all cars to pull away in the same direction in case of a fire. Well, in case of a fire erupting, if you are outside your vehicle, you'd better run fast, as there will be no time to abandon the hose, get in, start it up and drive away without being burned.
