the elitism in other comments is ridiculous, there is a market for this type of delivery services also because some people do not have the time to go to a restaurant, or to cook. Sure, you could lookup the restaurant online, hope that they have a website (they often don’t, only a Facebook or Instagram page), then hope that they do deliveries (which is a whole service that they have to add on top of their usual charges)

Elitist bullshit, sometimes it happens that people actually work long hours in difficult jobs and would like a little treat without having the time to actually go out. So yes, these services existing are a good thing. It’s not a laziness issue, it’s a privilege issue.
