User: Hi, can you please help me out with looking for some movie tickets?
Assistant: Hello, I would be glad to help you out, what movie are you interested in?
User: I'm thinking of watching either Parasite or 1917, I heard both are winning a lot of awards.
Assistant: Is there a theater that you would prefer?
User: I really like the Regal Theater.
Assistant: And what show time and screen would you prefer?
User: I want to see it in the morning, so around 10:00 AM is good, and a regular screen showing is fine.
Assistant: At Regal theater I've found a 10:30 AM show time for Parasite and a 10:15 AM show time for 1917, both on regular screens. Do any of these interest you?
User: Yes, I think the 10:15 AM show time for 1917 would be good, can you help me purchase tickets?
Assistant: Yes, how many tickets would you like?
User: Actually, I think I really want to see Parasite. Can I instead buy tickets for the 10:30 AM show time of Parasite?
Assistant: Yes, that's fine. How many tickets would you like for the 10:30 AM showing of Parasite?
