Have you people seen this 70 yrs old gentleman in Mumbai?
His name is Rajkumar Singhania and everyone calls him "Raju Bhai Paaniwala" with affection. For over 30 years, he has been serving free drinking water to the commuters of the local trains in Mumbai at CST Station/Masjid Bunder in evening. He washes the bottles of water thoroughly at home and carries cold water in summer and warm water in winter to serve to the thirsty commuters.
