Why does Frank make the effort to go up and down the street where Reid Press is located?

The reason Frank ventures up and down Seraphim Street, where Reid Press is located, is to ingratiate himself with neighboring firms. In this period in Moscow, part of the taxes a business pays depend on what neighboring firms have to say regarding the other businesses. As a step toward ingratiating himself, Frank agrees to pay for the cost of a night watchman for his entire block.
