Angie has gone to the same hair salon for the past ten years. She believes that her stylist, the salon owner, does a better job of cutting and styling her hair than anyone else could. Other salons have opened closer to Angie's home, some offering more plush facilities or lower prices, but she isn't tempted to switch. Angie's attitude toward the salon is an example of

customer loyalty

Explanation:

When a customer buys products or services from a particular company and does not buy the same product or service that is provided by another company the person is loyal to the company. This happens as the customer is satisfied only with the product or service of a certain company.

Here, Angie believes that her her stylist is the best at what she does and no other person can do the same better. She does not consider using the services of other salon's. Hence, Angie shows customer loyalty.
