The waiter supplied Kinley *L water bottle with MRP price of Rs. **/-. However, it was charged Rs. **/- (this is *** % higher than the MRP price) in the final bill. I asked the manager about this extra price. He said, the restaurant is following the law and pricing accordingly, although they charged much higher price than MRP.
