The book “An Angle of View of Reality” will be of interest to a wide range of readers interested in how the processes of retail trade and large sales occur in our reality. How the client sees the seller from his side and how the seller, in turn, perceives different kinds of clients. The roles of a person in the situation of “customer” or “performer”, ambivalence of behavior in different roles and diversity of perception of reality. What are the names based on, how do business processes work, what motivates a person to buy or sell. Stereotypes of the service sector, sales and employer-employee relationships. “Big marketing”, branding in “simple words” and manipulating the desires of target audiences. All this and much more in the book “An Angle of Reality.”
