Indian Railways — Illegally asking money at Ahmedabad station AC waiting room Toilet

Recently I have gone to my home town during which I have waited at Ahmedabad station AC waiting room. While using Ahmedabad Station AC waiting room Toilets for mouth wash . They are asking for money which is illegal.they have right to charge only for urinals, Bathing and for using latrines. But mouth wash or brushing tooths are free so why are they asking for money???
