If you manage a 200-room hotel and sell 150 rooms tonight, you cannot "stockpile" the extra 50 rooms for tomorrow or another day in the future to sell them. The term for this which we use regularly in the hospitality industry is?

Perishability of services

Explanation:

Perishability is the term used by marketers to describe the inability of services to be stored, returned, resold , or saved once a customer is gone. Unlike products, services are intangible. They can be touched as they do not have a physical presence.

The term perishable implies short-lived. It means services cannot be preserved for future consumption. Once a customer has consumed a service, that service is completely rendered; there is no reversing or alterations.  Services are short-lived in a sense they are assigned to be delivered as specific duration. For this restaurant, if the manager is unable to sell the 50 rooms for that night, he cannot preserve that service for another day.
