It's something you can do if you want to. Nobody will stop you as long as it's legal, so there will be a non-trivial amount of companies doing just that. It doesn't matter that the guy on the cornerr is trying to be fair. At some point he'll be screwed by a kebab chain which pays the minimum wage and can use the economy of scale in deliveries.
And that's even before we talk about companies that go for risk*penalty<gain situations where they can ignore the law.
