I know its parody, but the idea of Sliceline is objectively not a bad business model - lots of small pizza franchises could benefit from similar app-based delivery services, and would pay to be able to compete with Domino's on that front. I met a guy who manages an Indian restaurant that does dev work on the side - he's operating an online ordering/fulfillment service for 3 other small restaurants, and claims to take 7% commission from every order that comes through the system. Not bad if you ask me.
