Indian Railways — public toilet at chennai central railway station

Address:

Chennai, Tamil Nadu

Had my dinner outside and wanted to wash my hands. He said he won't allow me to wash hands inside. He said go wash your hands anywhere in the railway station except the toilet or pay money to wash your hands inside.
Even though the notice outside says urinal 2/- he charges 5/- and 10/-. The way he talks to people is very very rude.. I'm a 28 year old guy and when i'm saying it's rude then image people more than 35, how they should feel.
