reservation.

Agent: I know why we have reservations.

Jerry: I don't think you do. If you did, I'd have a car. See, you know how to
take the reservation, you just don't know how to *hold* the reservation and
that's really the most important part of the reservation, the holding. Anybody
can just take them.
