Grandfather sets up a bicycle repair shop.
Father expands the operation to include selling bicycles and opens up branches in other cities. By the time Son inherits the company, it has become a multibillion-dollar retail empire with interests in shopping malls, supermarkets and multiplex cinemas. But darling, that is so, so 20th century. Let's face it. It's survival of the fittest, baby, and the fittest are those who have the best ideas and the ability to run with them.
