I went for dinner at "Baujee Ka Dhaba" 18, Hauz Khas Village, New Delhi-110016. After ordering Dinner & Drinks we had taken a mineral water bottle of Aquafina from them. The same has been charged Rs. 35/ in the bill presented. When I tried to bring this to their attention that as per the norms they are not suppose to charge extra from the MRP mentioned on the product, they did not pay attention. I have retained the copy of bill. Please advise how to proceed with the case if it needs to be filed in consumer court.
