Yes. Nikhil, that's a good question. So I guess this is kind of how we've always thought about it. I mean I think, first and foremost, we think about it from the perspective of the customer and how they're going to judge us, right? And if you think about that, well, there are several factors. They're going to judge us based on what selection of retail offerings we give; certainly, the cost of getting fast delivery; as well as the quality of that delivery, both in terms of the timeliness, the accuracy and, especially with regards to something like grocery, whether or not we got exactly all of the items that they had specifically ordered in the condition that they would expect. And so if you think about DoorDash's journey or evolution in that process, it started by really introducing a new use case, both to consumers as well as to grocers alike, which was this top-up use case, right, where we solve for the middle-of-the-week run, where the items in your pantry that you consume the most often or the items that perhaps may have perished the earliest, such as fruits or berries or milks or yogurts or coffees, things like this. We really started with that category. And that not only solved a consumer problem that wasn't being addressed in the market at the time, it was also an incremental occasion for retailers. And that's why we're seeing quite a lot of pull. We announced a lot of additions to the platform in Q1, whether it was with Ahold as well as more recently in Q2 with Wakefern, and we added several dozen retailers in the quarter. And so I think, certainly, we're seeing increasing pull from consumers and from retailers. And so on the selection front, I think we're making the mark. On the logistics question specifically, I think of few things. One, we always thought that we had an advantage given just our Dasher density and the network that we've built up where the thesis would go, if you can build the largest network in the highest frequency category, in the category that has the most nodes for last mile delivery, i.e., there are more restaurants than there are any other category of local retail, then you would have a cost advantage. And that's certainly something that we've seen. I mean, in fact, I think the positive surprise in our grocery business has been that, even with smaller baskets and without a meaningful contribution from CPG ad dollars, we're actually seeing positive unit economics in our new verticals business. And so I think that's certainly proven out. And certainly, there's an advantage of the speed and the flexibility in which we can make this offering to consumers. But to your point, there is a trade-off sometimes with cost. Now we believe that we'll make quite a lot of progress in terms of equalizing what we can do versus what else is out there. But there's also this other dimension, right, which is the selection. So on the one hand, third-party is more expensive on a point-to-point basis versus first-party. But then on the other hand, it's faster and it offers more selection. You can certainly get offerings from more stores, for example, than just one single store. And so I think it's going to come down to what consumers prefer. We obviously are going to work on a model in which we can increase the amount of selection that we offer, reduce the cost in which that selection is made available, and improve the quality of the process. And I think on these dimensions, we've certainly done that. And I think that's why you see the results that we've outlined where I think it's a third straight quarter now where grocery has seen north of triple-digits growth year-on-year. And so certainly, I think we're seeing that retention and usage and high engagement from consumers. We believe that we're making quite a lot of progress on our fulfillment quality. And we're also making progress on the cost to serve. So all things are pointing in the right direction. So we're pretty excited about where things are headed.
