This will turn out just like when they banned smoking in bars. Everyone predicted chaos and the end of the world, but a year after that law went into effect, no one really ever thinks about it at all anymore. On the rare occasion they do think about it, it's to say, "Wow, this is so much better now."
I moved out of Jersey a dozen years ago, though I still work there. Given the choice, which is basically always, I fuel up in Pa. If it cost a few cents more per gallon (because of various Pa. taxes), I consider it a convenience tax. There is nothing like rolling up, getting out of the car, and getting right to it. Imagine the ridiculous amount of time you waste sitting there in your car like a dope waiting for some schmuck to come over and pump your gas, especially when he's the only one working and there are five other cars there.
And no, never once in 12 years have I ever had to pump my own gas in the rain. My car has a handy gauge that tells me how much fuel I have, which allows me to plan around having to do that. And I'm a terrible planner, but I still manage. I imagine most others would be able to as well. It's so much better having the ability to get in and out of there that quickly that it's actually a quality of life issue. It makes that much of a difference.
