A yet-to-be-released film comes up with a display ad offering a 25 per cent discount on admission rates. Has that ever happened before? Now, in the multiplex era, or in the single screen era? It has not. Ajay Devgn's 'Drishyam 2' opens on November 18, but the advance booking has already commenced and for those who booked opening-day tickets on October 24 and 25 were offered a discount of 25 per cent!
