Final answer:
Guarantees, warranties, and service contracts are explicit forms of reassurance provided by businesses to customers, which, along with unstated guarantees, create a comprehensive service promise.
Step-by-step explanation:
Guarantees, warranties, and service contracts are examples of explicit reassurance that sellers provide to customers. These are personal and nonpersonal statements about a service made by an organization. Not only do companies offer these formal pledges, but there are often unstated guarantees at play in the customer experience. For instance, a movie theater may not advertise a refund policy, but it could still refund the ticket cost to a dissatisfied customer. Similarly, restaurants typically do not have formal exchange policies, yet many will accommodate requests to exchange dishes or offer bill adjustments if a customer's expectations are not met. These gestures contribute to the overall service promise to the customer, enhancing their perceived value and satisfaction.
