It was the summer of 1965. DeLuca, then 17, visited Peter Buck, a family friend. Buckasked DeLuca about his plans for the future."I'm going to college, but I need a way to pay forit," 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 tenyears. After doing some research, Buck wrote a check for $1000. DeLuca rented a storefront(店面) in Connecticut, and when they couldn't cover their start-up costs, Buck kicked in another$1000.
