After queuing for nearly an hour, it was my turn to have CNG filled in my car, the car required 5.88 kgs of CNG which was filled at the rate of Rs. 66.75, that would been a total of Rs. 392.45, but I was asked for Rs. 410. On my inquiry, I was told that since there is no electricity, by the time my turn came I also had to pay additional Rs. 3 per kg because of the generator being used. Since I am an ordinary man and unaware of the fine laws or rules and regulations prevalent in my country, is this additional charging of Rs. 3 per kg fair and legal?
