Which are the worst petrol stations in Karachi with whom you have had a bad experience?
Bad experience = cheating, rude staff, low grade fuel, etc.
PSO Pump on main Korangi Industrial Area today tried to cheat me by giving me the wrong change. He gave back PKR 100 less. This is the pump near Clariant chowrangi. When I told him he gave me less change, he immediately handed over Rs 100 to me. I didn't even mention he gave 100 less..
