Final answer:

Step-by-step explanation:
The statement in the question is true. Guaranteed reservations made by telephone are confirmed on the spot, and the reservationist provides the caller with a confirmation number. This is done to ensure that the reservation is secured and to prevent any misunderstandings or errors.
Even though some reservations systems may send written acknowledgment to the guest several days later, the confirmation number given by the reservationist is considered the immediate confirmation of the reservation.
For example, when you call a hotel to make a reservation over the phone, the reservationist will confirm the booking by providing you with a confirmation number during the call.
