Next time you are at the Tasheel, or the Immigration Department, or at any place where you have to take a token to wait your turn, here’s a tip that could save you some time.
While waiting your turn do a quick scouring of the seats and the floor to see if there is a token lying around with a lesser number. Chances are that some people who take a token may have decided not to wait any longer. This could just help you to jump the queue. Make sure you have the token of the right queue !! I have had a good rate of success with this and hope it helps you too.
