Today morning on the way to office I experienced another cheating at a HP petrol pump. I asked for full tank refill and the guy filled 37 liters and was still going on till I asked him to stop. At that time I suspected foul play but I was not sure about the full tank capacity of my vehicle, but after reaching office I just checked that the fuel tank capacity of my i10 is 35 litres only . I am going to catch that guy in the evening
