User: Hey, could you book some movie tickets for me?
Assistant: Certainly, what would you like to see?
User: My sister and I want to see Parasite.
Assistant: So, two tickets then?
User: Yes, that's right.
Assistant: Where will you be seeing the movie?
User: We are in the Kansas City area.
Assistant: What type of screen would you like to see it on?
User: A standard screen will be fine, I think.
Assistant: What time would you like to see the movie?
User: 7:00 PM should work for both of us.
Assistant: Ok, so I have two tickets for Parasite on a standard screen at 7:00 PM?
User: Wait! I forgot that I have a squash game after work and probably won't be able to make that showtime. Is there a showing at 8:00 PM?
Assistant: Yes, would you like me to book 8:00 PM instead?
