> I don't understand how so many VC's fell for a supply chain concept that a first year Operations Research student would had figured out that is so inefficient that is not worth pursuing. Why not? From my understanding, individual restaurants were doing it for a long time with less efficiency (orders via telephone, staff would be idle when no orders are around and can't do orders for another restaurant during those times). Why wouldn't it be profitable to make that process more efficient?
