There's some benefit to the businesses in that people who otherwise wouldn't have heard about them can find them more easily. Personally I order a fair bit more frequently since I can pay by card and I rarely have cash at home. In the UK the most popular service is probably Just Eat and until recently they didn't have their own drivers. I assume this also meant they took a smaller cut of the order.
