David Haden's calling is more than selling suits at Mr. Mac

OREM — He can tell you how to stay cool in the tropics, avoid foot fungus in the jungle, beat the humidity in Rio de Janeiro, and survive a Siberian winter.

So what exactly does David Haden do? Teach geography? Anchorman on the Weather Channel? Work for the CIA?

Nope. He sells suits.

David is store manager at the Mr. Mac clothing store in the University Mall, where he has become a world expert on, well, the world.

His mainstay customers are Mormon missionaries. They stroll into Mr. Mac with their call to Pretoria or Peru or Portland in their hand and their mother with the family checkbook right behind them.

Then they run into David.

It's like running into an atlas that talks.

Name the place, he knows its climate, its humidity, its culture, its topography and whether it has a McDonald's.

If he hasn't been there personally, he knows people who have, and he has made it his life's work to keep all this information on the tip of his tongue so that no matter where a missionary is going he can outfit them properly.

In the process, he has become something of legend in his own time. His boss, Steve Winn, calls him "unbelievable." New salesmen crowd around and watch when he's helping a customer like rookies around the batting cage when Pujols bats. And the people he's served over the years? They're constantly sending him wedding announcements, graduation announcements, birth announcements, even funeral notices.

He's not the guy who sold them suits, he's family.

David tends to shrug off his notoriety as if anybody could do what he does. He is stationed, after all, in the heart of missionary country. BYU and the LDS Church's Missionary Training Center are just down the street. If you can't sell white shirts, ties and two-pant suits and sturdy shoes here, then where?

But nobody has done it for as long and as well as David. He started at Mr. Mac 30 years ago, when he was 29, and he's not even close to burning out.

"I remember after the first week I wondered how long I could do this," he says. "But the more I did it, the more I loved it. I have met some of the most wonderful people in the world in this store."
