     It was the summer of 1965. Deluca, then 17, visited Peter Buck, a family friend. Buck asked

Deluca about his plan for the future. "I'm going to college, but I need a way to pay for it," Deluca

recalls saying. "Buck said, 'you should open a sandwich shop.'"

     That afternoon, they agreed to be partners. And they set a goal: to open 32 stores in ten years.

After doing some research, Buck wrote a check for $1,000. Deluca rented a storefront (店面) in

Connecticut, and when they couldn't cover their startup costs, Buck kicked in another $1,000.

      But business didn't go smoothly as they expected. Deluca says, "After six months, we were

doing poorly, but we didn't know how badly, because we didn't have any financial controls." All

he and Buck knew was that their sales were lower than their costs.

     Deluca was managing the store and to the University of Bridgeport at the same time. Buck was

working at his day job as a nuclear physicist in New York. They'd meet Monday evenings and

brainstorm ideas for keeping the business running. "We convinced ourselves to open a second

store. We figured we could tell the public, 'We are so successful; we are opening a second store.'"

And they did-in the spring of 1966. Still, it was a lot of learning by trial and error.

     But the partners' learnasyougo approach turned out to be their greatest strength. Every Friday,

Deluca would drive around and handdeliver the checks to pay their supplies. "It probably took me

two and a half hours and it wasn't necessary but as a result, the suppliers got to know me very well,

and the personal relationships established really helped out," Deluca says.

     And having a goal was also important. "There are so many problems that can get you down. You

just have to keep working toward your goal," Deluca adds.

     Deluca ended up founding Subways Sandwich, the multimilliondollar restaurant chain.
