User: Can you get some movie tickets for me tonight?
Assistant: I can help with that. What movie do you want to see?
User: Dolittle
Assistant: What will be your location to see it?
User: I'll be in Denver Colorado.
Assistant: Ok, and about what time would you like to see it?
User: Something pretty late - around 11 pm
Assistant: Regal UA Denver Pavilions has a showing at 10:35 and AMC Dine In has a showing at 10:45. Would either of those work for you?
User: The Regal UA will be fine.
Assistant: Ok, and how many tickets do you need?
User: 6 tickets total
Assistant: Is there anything else you need before I book the tickets?
User: I changed my mind on the theater. I'd like to eat there, so I'll go with the AMC Dine in.
Assistant: I can switch that. Shall I confirm the details and order the tickets?
