User: Hello. I would like to book some tickets to take the kids to the movies tonight.
Assistant: I would be happy to be of assistance. Do you have a movie in mind?
User: Yes, the kids really want to see Spies in Disguise.
Assistant: Do you have a preference for location?
User: We are in San Francisco and AMC Metreon 16 would be ideal if that movie is playing there.
Assistant: Let me see. Yes, Spies in Disguise is indeed playing at AMC Metreon 16. Do you have a showtime preference.
User: Let's see. Is there anything playing around 4:30 PM?
Assistant: There is a Standard screen showing at 5PM. Would that work?
User: Hmm, I don't know. I was sort of hoping it would be playing in 3D.
Assistant: There is a 3D showing but not at the time you are looking at.
