The restaurateur understood the numerous disadvantages of competing against the chains. They purchased everything in bulk-lettuce,
meat, furniture. They even purchased newspaper ads and television commercials as a group. This, of course, meant they received better rates than
a little guy like him. Still, despite his inability to match his competitors' purchasing power or advertising budget, he refused to allow the chains to
monopolize the town's restaurant business. He saw their mammoth size as a challenge to think smarter and work harder. He strove to offer the
variety often lacking in the chains, and he established strong connections in the town. He believed his neighborly goodwill would allow him to
withstand the squeeze of the town's Goliaths.
