In India even in my early childhood, milk was freely available. To think of selling milk was inhuman, ugly, for the simple reason that there was so much milk in the country. Who was going to purchase it? And secondly, to sell milk looks bad because milk is nourishment, and if somebody is in need of nourishment and you are doing business, you are trying to exploit his hunger, his thirst. Food was not sold. If you asked for food you were invited to be a guest. And this was in my childhood, just fifty years ago.
