I'm with you- I grew up in upstate NY so very familiar with pumping my own gas. Have lived in NJ for 20 years now. And it is SO much better to have someone else pumping my gas- getting gas on their hands, stading in cold, heat, rain. And I can be sitting in the car listening to some good music, make a phone call, etc in comfort...
And it is NOT faster to do it yourself.
In most cases, if you use a card- you have to walk into the station prior to getting gas to pay for it - and what a pain in the *** if you just want to fill it up or, if paying cash, you still have to walk into the station after pumping to pay them.
