Each day in Mumbai, a group of men called Dabbawallas transport 175,000 homemade lunches from Indian homes to their family members' offices. They carry the tiffens ("lunch containers") on their heads, on bicycles, on trains and even across the tracks to get to the offices where husbands and sons of the ladies who prepared the food are awaiting lunch. Despite the various modes of transport, the lunches always arrive on time. It's a pretty impressive feat and we were lucky enough to follow a couple Dabbawallas for a day in Mumbai.
