Home delivery has been around in India for ages too. Not only for restaurants (for which it became common only some 10 or 15 years ago, IMO, though existed before too), but much more for small general stores - called kirana stores here - what are called mom-and-pop stores in the US. And the owners of those small stores, who often are from the Marwari community (at least in northern and central India) are very entrepreneurial.
