Answer:
Providing personal customer service
Step-by-step explanation:
Rudy provides his customers with very personalized service. His business model functions well because he has a sizeable amount of followers on his website. Rudy personally interacts with his customers, lets them knows his location and the menu for the day, and thanks them for their support. Since Rudy owns a food truck, he can move to different locations. By providing personalized customer service, Rudy is encouraging his followers to find where the food truck is located that day. This way, he gets the traffic of where the food truck is located that day, but he also has people that specifically go to that area for his food truck.
