Hopefully, NJ will never change its policy. We pay less for gas than they do in most other states AND we don't have pump it ourselves. Sounds like the best of both worlds to me, and creates more jobs for kids and immigrants in the process. I like not having to get out of the car on very cold or very hot days to have to pump my gas, or having to read the instructions about how + where to pay.
While I like having full-serve in NJ, I also realize that NJ has lower gas prices because NJ has lower gas taxes. Full-serve in NJ adds a little to the price of gas (less than 5 cents per gallon). To me, that is a nominal price to pay for the convenience of not having to get out of the car and pump my own gas.
Also, if you live in a self-serve area, you don't really need to read the instructions on how to fill the tank. You can learn it pretty quickly.
Incidentally, I had to get gas this morning, so I decided to see how much extra time I spent with full serve.
I pulled into a busy Quick Chek on my way to work and pulled up to an empty pump. I got out of my car, as if I were going to pump gas myself. By the time I got out of the car, the attendant had already opened the door to my gas tank and was approaching the driver side door. I handed him my credit card and he went to fill the tank. Certainly no time was wasted before gas was pumped into my car.
While my car was being filled, I went back to sit in the driver's seat. When the pump clicked off after my tank was filled, I noticed that the attendant helping me had just walked up to another car that needed gas. This was the worst possible outcome from a time perspective. I had to wait until the attendant was done with the other car before he could finish with my car. It took 27 seconds. Of course, when the attendant was done with my car, I was already in the driver's seat, and I started the engine and pulled away. If this were self-serve, I would have had to walk back around the car, get into the car, and put on my seatbelt before I could start the engine an pull away. I'm pretty nimble, so that may have only cost me 5 seconds (but judging from people pulling out of the supermarket parking lot, it takes some people 3 minutes or longer to get into a car and start to pull away). So reducing the 27 seconds I had to wait by the 5 seconds I saved by not having to get back into my car after fueling, I estimated that I lost a whole 22 seconds by using full-serve instead of self-serve.
