Tea is a serious matter, it requires much hard work and science to grow it, harvest its leaves, wither them, heat them, roll them, oxidise them, dry them, sort them and more. But tea is not just about that. It is also a simple drink, an everyday act, an affordable pleasure. Here, in Kolkata, this street seller, just opposite the New Market, is enjoying his chai tea. He’s drinking it from a little throwaway earthenware cup.
