Certainly, George. This is Todd. I'll start and then Mike can chime in. Gross margin in general, is up 40 basis points due to just energy alone, so that's obviously a headwind. I think gas stand-alone is up 60% year-over-year. But as far as the balance of that, the 70 basis points, we're making investments in the additional employee partners that we need to service the very nice growth that we're seeing along with the growth that we see coming. The revenue now, George, is different -- a little different from last year. It's much closer to our revenue -- our traditional revenue mix. And let me just give you an example because I think it'll maybe help you understand that a little bit better. With PPE last year there was obviously significant demand for that, and we're happy to help our customers with it. But in those cases, in many of the cases with that, they were simply a drop ship to those customers. And when you drop ship, those large quantities, it doesn't take a whole lot of work. It's just a drop ship and then you're able to book the revenue, et cetera. You think of that versus the level of employee partners that is required to service uniforms, facility services, first aid and safety cabinets, it simply takes more work. However, we welcome this shift as it provides more value to the customers than simply a drop ship. It's stickier business and long-term, they have better margin. So we like it. We like that switch, and we knew that, that was coming, and we've been staffing for it and guiding for it. All that said, as we know inflation is at a 39-year high. As I mentioned, energy is up 40 basis points. Our investment in growth for today and the future. And if you exclude the onetime gain of our operating -- our onetime gain from last year, our operating margins were up 70 basis points and our incremental margins are quite strong. So we're doing exactly what we had hoped and planned for, I guess, would be the way I would describe it.
