I'm glad you highlight that, Trey. I would say this is really just a testament to the discipline that our teams live and breathe each day. We went out with some messaging, sort of just some reminders and some playbooks to folks. When we saw that sort of a concern in the shutdown setting, just coaching people on how to manage through it, right, and what our team just did a great job resizing the business when it was appropriate, making sure that we were cutting costs, being disciplined. And obviously, some of the things we did to give ourselves a little extra flexibility more broadly as a company we talked about that, delaying wages, salary cuts for executives. Sorry, delaying wage increases and salary cuts for executives. Those were things that we thought were necessary just to give ourselves that flexibility. Clearly we did very, very well as we went through that sort of pause period. Since then, with the recovery that we've seen, we've reinstituted, the merit increases, we restored all those cuts that we made. And the nature of the resizing of the business is very specific to the locations. So we try to retain the staffing, making sure we weren't hurting ourselves strategically. Our ability to compete, our ability to win, we didn't want to undermine that by being too aggressive, because we don't believe that we've allowed ourselves to get fat in these markets. There wasn't a ton of a cut. So what you saw at the end of the day was I think some real flexibility in the core around comm that some of that will come back, obviously in terms of expenses. You saw about a third of our overall benefit being TBD. Now that ones bit more time to play out. The question remains, will it ever get back to normal? Will we ever travel like we used to? TBD, but certainly that we anticipate will come back to some degree over time. Then third, that was really the fuel expense. And obviously, there's been some volatility in the cost of fuel. So that will normalize to wherever it's going to normalize to over time, maybe not right away on that one either. But we didn't go back through this organization and make any real structural changes or massive cuts. Our focus was on making sure we were responding and being ready to move forward. At this point that seems things played out pretty well.
