Watching a 3D movie at Q-Cinemas can make you poorer by Rs. 30/- ;). This is the charge not specified in the tickets, but they charge service charge for providing you with 3D glasses, and also take an advance amount of Rs. 100/- for the glasses. What misleads this is that the charge is not advertised in their campaigns, where the charges are Rs. 130/- to Rs. 180/-, but in reality, it is more by Rs. 30/-.
So be prepared for it when you are watching a 3D movie at Q-Cinemas the next time.
