Yes. So, look, at the moment, we are available on Grub at all almost a less than handful of Shacks are not available. So, pretty much everyone across the country. We are still available on certain marketplaces for the time being on Postmates, DoorDash and Caviar. Although probably in the very near future, certainly in this fourth quarter, they will become unintegrated. So, whether they choose to keep us on their platforms or not, that will be up to them. But, our agreement with Grub is to only integrate directly and market with them. So, why would you that? For the same reasons we've been talking about, setting aside any other company decisions. Our decision has been consistent as we've talked about in the last few quarter's. And when we announced this in the last quarter, we were going after the greatest guest experience we possibly can, making sure that food gets there in the best way it can. And what we’ve seen with so many different platforms is that, it’s been more challenging for our operators, more challenging for our guests. So, we want to give a clear channel where that can happen in the best way possible. We also are going to benefit from the data that we learn about our guests, about Grub, people and how we can harness that. We are going to be able to directly market with them and that'll be exciting for us. We also believe over the long term, and this is -- we’re a long-term thinking company, we're not just going to jump on to the next quarter, that this has the best potential to be the best revenue we can get. And then, lastly, the overall improved economics that we expect to our Grub deal, they will be better in the OpEx line than the economics we've had in various pilots over the last few years. So, all of those things together, this is the next step. It may not be the forever step, we may, at some point in the future reconsider that as we learn. But today, it’s the next step we’re making. It's an important one. And we believe, it's the right step for Shake Shack today.
