User: Hey! I'm curious to see the movie Sonic. Can you tell me when it's playing today?
Assistant: Sure! Let me look up the times. What theater are you considering to go at?
User: I was hoping to see it at the Cinemark in Aurora. I don't think I want to go to the Regal anymore because of the uncomfortable seats.
Assistant: Sure! Let me look They have showings at 315, 720, and 1010. Which one would you be interested in?
User: I think the 720 one will do. I wont be able to get out of work in time.
Assistant: Gladly! Would you want in standard, 3d or Imax?
User: I believe I will want to check the IMAX version. I'm curious how this will roll.
Assistant: No problem let me get that set up for you.
User: Thank you very much. I'm hoping to see it with my spouse. I forgot to tell you how many tickets
Assistant: Yes I'll book two tickets for the 720 showing of Sonic in Imax.
User: Perfect! Oh WAIT
Assistant: What is it?
User: Could you change it to standard? I think IMAX will be too costly.
Assistant: Certainly, I can do that for you
