yeah guys watch sar e aam video which show hows they make people fool i have also been affected by like this on shell pumps its better to stand near the dispenser and watch the whole reading and dont try to talk ever with these guys unless ur required quantity is filled in this way you will be able to stop these guys but still u cant do anything with software or mechanical changes or mixture of water/other chemicals made with the dispenser by the pump owner normally pumps with such fraudulent alterations do not give the fuel in bottle
