Super woman to the rescue!

We set off for a long drive on a weekend, in a Chevy that we had rented for the weekend. Before it is late we realised that we have not checked the gas station and the needle was already reaching for empty. Luckily , we saw a gas station nearby and went there. Being not so used to Chevy, we had a hard time trying to locate the lock release for the gas tank.The gas station was deserted and it was already getting darker.
After quite a while,we saw a gang of chics parking their chevy in a nearby aisle.We had no choice but to ask them for help. Two of them came to help us checking again the every control that we had hoped will work, in the past 10 minutes .
In vain,they exclaimed, "Its unbelievable !"
It was a brand new vehicle, hardly wud have run 1500 miles. They said , " they release a new model every now, we r sorry , we gotta leave!"
Just then , an old lady parked a Toyota behind us. She was waiting for her turn and watching the four of us in despair , sensed that her turn was never gonna come. She got off the car and headed straight to the gas tank of our Chevy and in a snap , slid opened the gas tank , much to our awe.
She didnt speak a word , neither was she waiting for a 'Thank you' from us. Much relieved , we waved thanks to her and soon cleared from there. I m not sure , if the model was new , Hats off to the lady , anyway.
