Anil Thadani, the all-India distributor of Tanhaji: The Unsung Warrior, has asked single-screen cinemas to charge Rs. 20 for 3D glasses instead of Rs. 30 per patron. However, multiplexes have been allowed to continue charging Rs. 30. This is causing a lot of heartburn among single-screen cinemas as they have been so far charging Rs. 30 for other 3D films too.
