Hill: I'm glad you mentioned Grubhub. It really does seem like we're at a point now where, if you own a restaurant stock or you're thinking about buying a restaurant stock, one of the questions you absolutely need to ask as an investor is, what is this company's strategy when it comes to delivery? They need to have one. And it's not to say it's the same answer for everyone. But in some cases, it does make sense to partner with a Grubhub and outsource that. Others are trying to do it on their own. Again, it's not that one size fits all. But if they don't have an answer to that, that goes on the negative side.
