Indian Railways — Charges levied for using urinal in ac waiting area at Ahmedabad

I was levied charges for using urinal in ac waiting area in Ahmedabad railway station. Since I have used AC waiting area on other railway stations of western railway and was never charged prior; I found charges levied to me as suspicious.
I needed confirmation whether divisional regional manager of Ahmedabad has authorised rest room facilities of ac waiting area to be converted to pay and use facility ? Or someone has fraudulently converted ac waiting area restroom of ahemdabad to pay and use facility ?
Also the attendants were very rude of Ahmedabad railway station waiting area
