Etiquette and respect for other…

I was queueing up to fill some gas, and in front of me there was a Suzuki Vitara, license plate #713648. Waited for 5-7mins… and there was a woman getting into the car with two bags of groceries….and then filled the car with gas… very disrespectful… meanwhile there were 3 cars waiting in line.
.. I was one of those.
