The competition of cafes

Last Updated: 2024/11/08, Three cafes live on the same street in New York at the same time. The first cafe put up a sign in front of his door, the best cafe in New York. When the second house saw it, it quickly hung the best cafe in the country in front of its own store. After careful consideration, the third company launched its own sign, the best cafe in the street, and its business has since far surpassed that of the first two. What do you learn from the story?
