Read the following context and answer the question.
Context: I ' m glad I made a reservation - there was an hour and a half wait for anyone else at 5:30PM . We were seated next to the Volcano Bar which has a working volcano overtop of it . We both had cheeseburgers and yummy drinks . The food was really quite good and fast , I was surprised .
Question: Why would having a reservation have affected our waiting time ?
Answer:


A reservation actually " reserves " your space and alerts the staff you are coming which gives you first seating .
