It’s not like we’re carrying sand and gravel. You know, we’re carrying chemotherapy drugs, and important manuscripts, and electronic parts, and pieces for airplanes that are grounded. So when we pick it up and say, “We’re going to have it there early the next morning,” I mean we have to deliver. There’s nothing else to it. So putting the guarantee in place was much more important internally than it was externally. Because most of our customers — based on the experience they’ve had with us — they believe we’ll do it. But it’s when we said to all of the employees, “This is guaranteed. If we don’t get it there, we don’t get paid.” That made it very clear to everybody what they need to do every day. We manage the continuous improvement in a mathematical manner every single day. Our service gets better each year. That’s very rare for big service organizations. Most of the time, as they get larger service deteriorates, it doesn’t improve.
