allow me to share a couple of experiences i rmember (obviously the bitter ones
1. BP pump in hoody, bangalore -- always avoided it, but that day i had to.. i asked to fill up of 1000. he filled up 400 and stopped. I said, boss 1000 bola tha, he went up to 600 and stopped. I just looked at him and smiled. he understood that I know his trick, and silently filled up till 1000. But the ordeal disnt end there. After that whenever car was going in 5th gear or >50kmph (approx), i could hear knocking from engine, the acceleration was slow, so stopped at the first good mechanic, and he told that the petrol was not pure and is adulterated, so I had to drain of the petrol and fill again
2. was going to mysore with a friend and his family. had planned to fill it up at shell pump on mysore road. But since that was closed, stopped by IOC bunk ahead. The kid of my friend was not feeling well, so we were looking at him, when the service attendant claimed to have filled up. This happened in a couple of moments. I was not sure as I had calculated it would gulp in 25 litres, and that much cannot go in few seconds. So I asked him to verify it, but he had by then already reset the pump to 0. So while my friend was attending to his kid, I parked my car nearby with engine on, letting the fuel gauge re-calibrate. To my astonishment, the gauge somewhere near the half way mark. When I showed that to the service assistant, he started a quarrel with me claiming my fuel gauge is faulty. At this time other motorists had also joined in to see what the commotion was about. Finally I asked him to try filling more, and if my gauge is faulty and the tank is indeed full, petrol will overflow and i will pay for that extra. But if the tank still gulps more and more, then boss you are at fault and accept it. To this suggestion he started abusing me in kannada, with some localites standing up for him. But then there was a long line of vehicles behind, and the pump manager asked him to fill the tank. No questions asked further and it was done. Since first reading was reset to 0 unethically my attendant, i paid only for 25 litres which I think was empty, and drove off with a promise to never go back there again.
