I think there -- what I'll do is, I'll take the first question and maybe have Sandeep lean in on the second one. I think on the lower income customer we're going to have to continue to watch, but my guess is, it's a little bit about both of what you talked about. It's going to be softness on spending. We see what's happening with credit card debt and payments are taking a little bit longer to go through. But we also saw more competitive activity, particularly in August. And I think it was both external and internal. So in August, we saw really through two of our competitors, major competitors, one of them had free delivery. The other one did their version of our Emergency Pizza, obviously qualitatively my preferences for ours. But those were two really good value promotions. Now at the same time, and I know this wasn't part of your question, but I think it's important to explain to everyone on the call, in August we did what we intended to do, which was -- actually we went with a quality message. You remember the [Simon Cowell] (ph) spot that we put on there. And we wanted that quality message for a couple of reasons. One, with Hungry for MORE, in order to deliver on our promise on the M, which is that we're going to have the most delicious food, we have to continue to beat the best, which is us, in operations. And so you'll remember last year we had Summer of Service. This year we've got three product sprints. And so the intent of that ad in August was not only to tell consumers, you know what, we've changed our stores, we've got these quality captains here now to make sure the product is great before it goes in the oven. But it was also the bar was raised for our franchisees. We let them know last year, hey, when we're all done with this training, we're going to go on and we're going to make a promise to customers. And I think that was a little bit added motivation. So in August, what you saw is steps of competitive activity. We went a little bit more towards product quality, but then we very quickly, after about three, four weeks, went into more inflation back to value.
