Dennis, it's Kevin. I'll take a stab at that and Steve can chime in. As far as progress or opportunity, I think, as we've talked about, certainly one of our biggest opportunities continues to be at breakfast. As Steve talked about, there's been a lot of new entrants into that space. So, there's not many players that are growing, comp guest count at breakfast, or really in most of the dayparts. But new entrants have kind of caused a scattering, I'll say, of the existing guest counts among just more units. As far as retain, regain convert, the convert strategy for us was always around kind of opportunities in either other dayparts or other areas that we didn't have our fair share, if you will. So areas like coffee and snacking and areas that are potential further growth opportunities, but we're not as strong in some of those areas. It wasn't necessarily taking some of our existing customers and just having them come more frequently. So, there still are opportunities in some of those areas, again, like coffee and like snacking. I think, the way, we think about it is, there's an opportunity, and this is what kind of one of the purposes of both EOTF and our digital is to take our existing relationship with customers, and expand that relationship through digital means, whether that's through apps, further loyalty program at some point. But, the whole customer relationship where we can get to know and personalize offers easier and better for existing customers. That's one of our big opportunities. The U.S. guest counts will continue to be a, we call it a street fight just because it's a very competitive environment here in the U.S. But, I think, there is more of a focus on what do we need to do in the various dayparts. Again, breakfast probably being the biggest opportunity for us to regain some of those guest counts that we lost. And it really is about, we call it losing guest count, but it's not losing customers, it's losing customer visits. So, it's customers that may not be visiting us as often as they were historically. And if we can regain some of those additional visits, especially a breakfast time, which is, as you know, a very habitual ritual. And so, if we can get those customers coming again at breakfast, it would be a huge benefit.
