a customer calls and asks the cashier for a ticket reservation. The cashier tries to find suitable seats in the ticketing system's screen plan and suggests any available seats to the customer, which confirms the suggested seats. The cashier then blocks the confirmed seats in the ticketing system, which now generates a reservation for the seats. The cashier informs the customer about the reservation number, who is happy to hear that the tickets for the upcoming game are now reserved in the system.
