Missing info is
1. If these guys pay taxes or charge GST on food delivered.
2. How many units they deliver each day
3. What the cost of delivery of each unit and what's the value of the food content?
1. If these guys pay taxes or charge GST on food delivered.
2. How many units they deliver each day
3. What the cost of delivery of each unit and what's the value of the food content?
2. Article claims roughly 200,000 deliveries per day.
3a. Cost of each delivery is Rs. 800 per month / 24 working days = approx Rs. 33 (or less than half a dollar) per delivery. Normally the delivery involves a pick up as well (previous day's container is picked up along with today's delivery).
3b. Value of food content is irrelevant – it can be super expensive or dirt cheap, dabbawalas only care that it is packed in certain types of containers.
