One month before CID arrest one of my friend who was using his private car as a taxi in evening time in Doha...Now Karwa drivers will ask more money than before ...now they know thay poor people have no more option than Karwa taxi...we come from Doha to Alkhor in day time karwa drivers ask for 10 QR per person but if when we come after 9 pm they ask for 20 to 25 QR per person..
