​The dabbawalas (also spelled dabbawallas or dabbawalla called tiffin wallas in older sources) constitute a lunch box delivery and return system that delivers hot lunches from homes and restaurants to people at work in India, especially in GUNTUR. The lunch boxes are picked up in the late morning, delivered predominantly using bicycles and railway trains, and returned empty in the afternoon. They are also used by meal suppliers in GUNTUR, who pay them to ferry lunchboxes with ready-cooked meals from central kitchens to customers and back. The Lunchbox is based on the dabbawala service.
