User: Hi, I'd like to order some movie tickets.
Assistant: Ok, what movie would you like to see?
User: I'd like to take my little sister to see Frozen II
Assistant: Great! So, that would be two tickets then?
User: No, my boyfriend is coming along actually.
Assistant: Ok, three tickets for Frozen II. What time would you like to see the movie?
User: I think that 6:00 PM would be a good time.
Assistant: Would you like to see the movie in 3D or standard format?
User: I think she would enjoy the 3D experience.
Assistant: I'm sorry, there isn't a 3D showing at 6:00 PM. Would you like to change the time or format?
