PVR Cinemas — Disciplinary action and food items

Address:

PVR CINEMAS, ATRIUM MALL, HYDERABAD

I went to movie today and i was not allowed to take a Chocolate Inside the theatre.
The security guard took my item and said that he will return it later but he didn't do it.
Later i went to ask him about it and he provided me with wrong item and we had a quarrel for which he didn't apologize.
Aren't we allowed to take a Chocolate Inside the theatre and the behaviour of security was too vulgar.
