PVR — No bill provided for food we ordered.

I had purchased a popcorn combo, redbull and one more drink.

I had asked for the bill at the counter twice. The guy at the counter said that I will be given the bill with my order on my seat, but even when the order was given he did not give me the bill.
According the policy providing a bill to the consumer is necessary.
Also canned drinks are sold at MRP but the charges were more for the redbull and other can.
I request you to please look into the matter as soon as possible.
