Some doctors charge patients for missed appointments because the service value existed only at that point and disappeared when the patient did not show up. This is an example of which one of the following service characteristics?

Correct option is D

Perishability refers to the fact that services cannot be stored or saved for later use. In the case of missed appointments, the service value (the doctor's time) is lost once the scheduled time passes, which is an example of perishability in services.
Information Booster:
· Inseparability means services are produced and consumed simultaneously (e.g., a haircut).
· Intangibility refers to the fact that services cannot be touched or physically measured.
· Variability implies that the quality of services may vary from provider to provider or from time to time.
Additional Information:
· Perishability is a significant challenge for service industries like healthcare, where lost service opportunities cannot be recovered.
