Indian Railways — Vendor in faridabad station platform 3 trolly 5 overcharging

Address:

Faridabad Railway station,plaform 3,trolley 5

Respected Authorities,
Today i faced an unfortunate incident at faridabad railway station platform 3 stall/trolley number 5.
I requested the person on this trolley number 5 to provide me veg patty. This person rudely asked me to pay 20 rupees for it.When I objected that the price is higher than what other vendors are charging for the same patty, this vendor started misbehaving with me.He refused to show me the rate list. When I clicked photo of his stall this vendor physically assaulted me by pushing me asking me to leave his stall.
I request concerned authority to look into this matter and take action against this vendor of trolley 5 platform 3 faridabad station.
Had there been a rate list on this trolley this unfortunate incident would have never happened and I would have never gone through this humility.

Thanks
