Query: user: There is an Expo coming up in Washington that I would like to attend and need to find a train ticket to get me there from Chicago.
assistant: I am happy to help, just tell me the date you are planning on leaving.
user: I would like to go there on the 9th of this month.
assistant: The first ticket I found leaves at 6:20 am costing $106.
user: I only need 1 seat, can you find me something else?
assistant: There are 5 others starting with one that leaves at 11:50 am costing $109. Does that interest you?
user: IT depends, what station does this train arrive at?
assistant: This train is scheduled to arrive at Union Station.
user: Okay, and what station does it leave from?
assistant: The information I see here shows it leaving from Chicago Union Station.
user: That works for me.
assistant: Is there something else I can look up for you?
user: Yes, I would like to go ahead and book the tickets for that train ride but I would like the tickets to be conditionally refundable if possible.
assistant: Okay, I can do that. First let me just make sure everything I have is correct. You would like 1 Value ticket for the train that is leaving Chicago on March 9th, at 11:50 am, and travelling to Washington. Does that sound right?
user: No, I would like economy premium tickets instead.
