Final answer:
A reservation cancellation policy requires an agent to be at the venue 30 minutes after in case a consumer arrives late.
Step-by-step explanation:
The type of event that is being described in the question is a reservation cancellation policy often used in the service industry, such as hospitality or entertainment. This policy requires an agent to be at the venue 30 minutes after a scheduled time in case a consumer arrives. It is intended to ensure that the consumer is not left waiting if they arrive later than expected.
For example, in a restaurant setting, if a customer makes a reservation for 7:00 PM, the cancellation policy may state that an agent must wait at the venue until 7:30 PM in case the customer arrives late. This allows for flexibility and customer service in case of unexpected delays.
