Dabbawala

A dabbawala; also spelled as dabbawalla or dabbawallah, (tiffin wallah in older sources); is a person in India, most commonly in Mumbai, who is part of a delivery system that collects hot food in lunch boxes from the residences of workers in the late morning, delivers the lunches to the workplace, predominantly using bicycles and the railway trains, and returns the empty boxes to the worker's residence that afternoon. They are also used by meal suppliers in Mumbai, where they ferry ready, cooked meals from central kitchens to the customers and back.

In Mumbai, most office workers prefer to eat home-cooked food in their workplace rather than eat outside at a food stand or at a local restaurant, usually for reasons of taste and hygiene, hence the concept. A number of work-from-home women also supply such home-cooked meals, delivering through the dabbawala network.
