Sometimes I wonder if this whole food delivery boom is being supported by millenials who simply haven&#x27;t faced the need (or desire) to budget yet.  How sustainable is spending $25 per person per meal for those outside the top quintile?  I know it works in San Francisco and NYC, but how deep is the market elsewhere?  Or does that not matter?  Maybe a significant number of them will never have families and all that disposable income will go to postmates and doordash instead.  Maybe these businesses are built on price insensitive folks in urban areas for regular usage and irregular usage from everyone else?
