. This means that customers who are closer to the service center are more likely to be influenced by its services, promotions, and reputation, while customers who are further away may be less likely to consider the service center as their first choice.

As distance increases, customers may be more influenced by other service centers or competitors that are closer to them. This is because the convenience and accessibility of a service center play a significant role in customer decision-making.

In order to expand their sphere of influence, service centers can implement marketing strategies such as targeted advertising, promotions, and partnerships with other businesses to reach customers who are further away.
