User: Hello
Assistant: Hi there! How may I help you?
User: I'd like 2 tickets to go see 1917 today.
Assistant: Sure! What theater would you like to attend?
User: AMC, preferably in the downtown location.
Assistant: Ok, what time would you like to go?
User: Anytime around 8 PM.
Assistant: Closest showtimes for 1917 today are at 7:15 and 8:15 PM. Are one of those choices acceptable or would you like to see all showtimes for today?
User: 8:15 PM will be just fine.
Assistant: AMC offers both the standard and IMAX screening of this movie. The IMAX costs an additional fee of $3. Which would you like to book?
User: I'd fine with the standard.
Assistant: Ok, you are all set. Would you like to print your tickets or pick them up at the theater?
User: I'll print them. Wait, can you change it to the IMAX screening?
Assistant: Ok, I will need to cancel your original booking and re-book the IMAX screening.
User: Ok, thank you.
Assistant: Sure! I have cancelled your standard booking and re-booked two tickets to the IMAX screening of 1917 at 8:15 PM. Can you confirm this is your desired showing?
User: Yes, that's correct. Do I get to choose my seats?
Assistant: Great! Yes, you can choose your seats when the tickets show up in your account. You have chosen to print the tickets yourself, correct?
