The other day I went to get petrol filled in my scooty. I noticed the guy ahead of me got petrol for Rs.60 and he gave 6 notes of Rs.10. My turn came. I took my scooty forward and asked him to fill petrol worth Rs.200 as the tank was almost empty.
The guy asked me to put my scooty on the stand. I was a little surprised, nobody asks you to put your scooty on the stand. I said, 'there is no need to do that, I am holding it.'
And then I noticed that the counter had already reached Rs. 130!!!!!
I asked him why didn't he ask me to check 0 before starting filling the petrol. Then I realized that he asked me to put scooty on the stand to engage me so that I don't notice and he started the meter after Rs.60, which was the amount paid by the previous customer.
I asked him to fill in more petrol worth Rs.130. He started arguing. I took out my phone and was about to unlock it, he said sorry and filled the petrol.
I suppose he tried to cheat for 60 rupees, he had to suffer a loss of 70 rupees. (130-60=70). He didn't ask me to check the zero on the counter. His mistake!
