User: I want to get some tickets to the IMAX theater.
Assistant: Sure. I can help you with that. Do you know the movie you'd like to see or do you need to know what is playing?
User: We already know we want to see Hidden Pacific on an IMAX screen. Although Out of Bounds sounded pretty good, too.
Assistant: Okay. Do you have a theater in mind?
User: Yeah. We want to go to the Pacific Science Theater
Assistant: The showtimes for today are 10:30, 11:45, and 1:00 PM.
User: I think we want the 1:00 PM show.
Assistant: Okay. And how many tickets do you need?
