PVR — food products

With refresh to my movie experience yesterday, i had bought raw pressery juice which is worth of inr 90 and i had bought it for mrp 240 which is almost 3 times more than the actual price of the product. Why are these people charging us so much, and moreover we can't bring our food to too which is also not fair. This happened in pvr cinemas sujana mall, hyderabad. Please take action as soon as possible because they are charging teh amae way for every other products too
