Simple answer, no, it's not more challenging. There's ample opportunity out there. What is challenging is in the last 15, 16, 17 months of the proposition I'm talking to a customer moving in with them, when they want to be distanced from everybody on the planet. Imagine having an apartment, you bring in a roommate it's kind of the same concept. You just don't -- you don't want to be around people. And that's changing. And so seeing that expand, some things that, if you think about vending, which we've been doing now for 13 -- going on 13 years, when vending really took off for us, in that latter part of 2011, 2012 standpoint. In the following year, we were pulling out 25%, 28% of the devices that we would install, because some of them are just bad. And we didn't know what we didn't really know what we're doing yet, because we were creating an industry. And then that went to 22%. And then it went to 18%. And then as our participation and our knowledge base across the organization improved today 13 years later, we remove every year about 12% of our devices. We think we can get that to 10 with our list strategy, and some of the things we're doing to make it a little bit easier to serve FMI devices, but we think we can get that 10, but it's still 10%. The real question is what is that natural number for Onsite? And five years into a really hard push, unfortunately, a year plus of that five years is COVID. And so I don't know that we know what that number is. Now, we do know that about half of the Onsites that we close are because the customer moved the facility or closed down the facility. And the other half are, we pulled some back, we lose some visitors. So, there's a number of dynamics. There's some where we grow it from 30% to 60%. And we get stuck at 60%. And as Holden mentioned a few minutes ago, we've just moved back to the branch, because it's more efficient for everybody. Or the customer kicks us out, because they're out of room. And I don't like Onsite closers, but I know and I don't like FMI devices coming back, but I know it's part of the business, and the real question is, can we as an organization, over time, outgrow our industry can gain market share more efficiently, more productively, and we'd be redundant quicker than everybody else, so we can do that with Onsite and FMI devices and all the things we're doing. I love the business.
