I am sure you must have not confronted like this while travelling in metro. 

In a shocking incident, a man caught relieving himself inside Delhi metro and he claims that he has done nothing wrong. 

Much to the shock of everyone in the train, the man replied “This is the last train, so I could not afford to miss it”. 

Though the other passenger reprimanded him, he seems to have no regrets and replied in a harsh manner.
