Final answer:
Victor's approach to customer relationships aligns with Relationship Marketing as he focuses on building long-term connections and providing personalized value to his customers.
Step-by-step explanation:
The marketing concept most closely associated with Victor's approach to customer relationships is Relationship Marketing. Victor's methods emphasize building long-term relationships with customers, which involved personally knowing his customers, attending significant events in their lives, and providing personalized value such as free pizza on birthdays. This approach is about creating a strong, emotional connection with customers, rather than just focusing on individual sales. By contrast, Mass Marketing targets a broad audience with a one-size-fits-all message, Transactional Marketing focuses on maximizing individual sales without necessarily building a relationship, and Digital Marketing uses digital channels to promote products or services.
