I find it very hard to believe that woman has been driving for even a SHORT amount of time and hasn't encountered a self-serve gas station before!
My parents used to own a garage/gas station/convenience store and I started working there when I was about 13. Pumping gas is NOT difficult.
However, figuring out what side your gas tank is on..... that's a whole other story.
Our local gas station is set up with quite narrow lanes which I first observed at Costco, and now are popping up all over the place. You are only supposed to enter from one end, and exit on the other. Each gas lane has two pumps - forward and rear, and several HUGE yellow arrows indicating the direction, and which way you turn when you pull forward to "EXIT==>" per the big huge sign and arrow. The single exit lane is a narrow drive which is hard to pass two cars through, and also has another gigantic arrow and "EXIT" on the pavement. I'm pulling up to a "front" pump when some huge minivan comes squealing around the blind side of the pumps to try to go the wrong-way down my gas lane.
I can't tell you how many people I saw driving around the pump islands because they got out and realized their tank was on the OTHER side.... They'd then come around to the next island, get out, and OOPS! Other side again!!! We'd get quite a chuckle out of the folks who did this quite a few times before just driving off.... Apparently our pumps didn't work with their cars. I can only imagine how this one-ways thing will mess with more than a few minds out there!
I didn't learn how to pump gas until I was 21 (started driving at 17) I'm from NJ, land of full-serve only, and although I went to school out of state, I didn't have my own car until then. And if I was with my parents, which I was, on plenty of out of state trips, my dad always filled up the car.
But, knowing I didn't have a clue, when I got to school, I asked a friend who did know how to go with me, and show me how to do it. so that when I had to, I wouldn't stand there going, duh, duh, what do I do? even now, 30+ years later, when I travel out of state, I still have a moment of "how does THIS pump work?"
As for the gas tank side, I bought a new car last spring, with the gas on the opposite side of every other car I've owned. I can't tell you how many times as I drive up to the gas station, I'm telling myself "driver side, driver side"
So it is possible to go through life not knowing how to pump gas, but, its easy enough to learn, if you choose to.
