Reservations could indicate that a person is having doubts about a situation. At the beginning Brianna declined Brian's invitation to the ball because she wasn't sure he wasn't an ax murderer. In truth they had just never met before and buying a ball gown for a first date is a big investment. Reservations can also mean calling ahead to save accommodations. When the pair finally had their first date reservations were not made ahead of time and so rather than stand awkwardly waiting forty-five minutes for a table at Firebirds they called an audible and got seated quicker at Buffalo Wild Wings. So you see the story of Brianna and Brian is built largely around that term reservations. Thankfully it was found that Brian wasn't an ax murderer although he still doesn't call ahead for reservations. We might make it to Firebirds one day.
