PVR Cinemas — Harassment

We booked today show at PVR curo Jalandhar for evil dead rise at 10.45 pm.
We had to left the show in middle as cinema has allowed drunk people and they were shouting all the time
We complaint with cinema staff but they were not much bothered.i was with my wife and they were not bothered of a female security concern
Big question is that why cinema is allowing drunk people inside the cinema hall
