Tiffin in Trains

Indian Railways is known to be the third largest railway system in the world escalated the tracks from Kashmir to Kanyakumari. People travel upto 3 days by trains and need to do their regular chores in train obviously.  Lakhs of people  travel daily in Trains thats why govt. of India had set the prices of all the commodities in train lesser than outside it. But where the emperor of India "Corruption"  will go?
The vendors of food, water, confectioners, etc are looting people in the day light. Every year, with the Railway Budget, the prices of each item which is sell in the train is set and that is lesser than the MRP. But unfortunately most of the travellers don't even know this and vendors befool them and they accept it as their fate. This is the condition of "Blind Aware Crowd" of India. Both the people and the Govt. are swallowing this fact and shouts over each other regarding the rise in prices.
If we will assume that around 500000 people travel per day by trains and buy anything then if each traveller is giving Rs.5 extra to the vendors unknowingly then the amounts equals to 25 lakhs per day. Govt.  says that we need money to level up the quality of Indian Trains and we should raise prices. Why these type of small corruptions are not being stopped by the govt. along with the hands of people.
Think about it.
