Kelsey Guthrie didn’t need to know that milk, yogurt and dairy products are shelved from the back, to keep older stock from ending up unsold.

Or that Checkers Foods gets up to six shipments a day, all flowing through a fast-paced loading dock in back.

Or that the store’s freezer gets down to 15 degrees below zero.

No, the astute listener had soaked up plenty of information during a tour of the store Tuesday morning, but she still found herself hungry for information as Checkers owner Jim Lewis paused to take final questions.

Guthrie, who could’ve passed for a shareholder addressing management at the Disney annual meeting, didn’t miss a beat: “Where do you get the money to buy stuff?”

Lewis, the CEO, looked down and smiled.

“You have to have some money to start with,” he said. “You buy stuff, and then you sell some things and you make a little bit of money so you can buy more things.”

Guthrie accepted the answer without pressing for explanations of the store’s supply-chain logistics, profit-margin levels or other business minutiae.

She didn’t need to.

The second-grader figures she’s got plenty of time to figure that stuff out.

Broken Arrow School second-graders watch -- and eat cookies -- as Rebecca Sturgeon, a baker, makes tortillas at Checkers Foods, 2300 La. About 40 students toured the grocery store Tuesday as part of a business-education unit.

“I’ve learned about stuff that’s important,” said Kelsey, as she left the store. “It’s really important. People need food to survive.”

Kelsey was among 40 second-graders from Broken Arrow School to tour the store Tuesday, part of a walking field trip that also stopped by Douglas County Bank, Westlake Ace Hardware, Image Works and Pancho’s Mexican Food in The Malls Shopping Center.

The trip closed out the students’ latest business-education unit, A World at Work, which exposed the youngsters to basic business concepts, said teacher Pat McAlister, who taught the unit along with fellow teacher Mary-Nell Gleeson.

Students learned about consumers and producers, and the different jobs needed to keep the two sides of business transactions flowing.

“We’re all consumers,” McAlister said.

Lewis remembers going through a similar program as a second-grader, having toured Drake’s Bakery in Ottawa.

He’s pleased that such educational opportunities endure.

“This is something these kids will remember,” he said.
