Police welfare petrol pump on Montgomery Road Lahore is run by Police. They are also Chor and try to rip of where ever they can. They try to fool this way:
You - "Please fill Rs. 1,000 worth of fuel"
After filling like two litre they will stop.
When you ask what happened?
Police - "Sorry we thought you asked for Rs. 200 petrol"
Then they refill additional Rs.800 and claim full one 1,000. You get two litre fuel plus fuel for Rs.800. This way they rip off about Rs. 70.
They tried this twice with me.
Its always better to be watchful on the meter
