Where will you be traveling to?
I will be going to Broxbourne. 
I have 2 trains going to broxbourne, do you have an arrival time preference?
i just want to leave after 21:30
Will an arrival time of 22:01 work for you?
Yes, that would be fine. I'll need the price and travel time for that, please. 
will you be leaving cambridge?
Yes, I'll be leaving from cambridge. What's the train number and cost? Oh, and how long is the trip?
It costs 17.90 pounds.  I need to know your arrival time to determine the trainid.
I also would like to book a table for 3 at prezzo for 16:00 the same day I arrive or Tuesday. I need the reference number also.
I was able to reserve a table at Prezzo on Thursday at 16:00. The table will be reserved for 15 minutes, reference number R0Q4HL63. Can I assist with anything else? 
No thank you that will be all
Have a nice day.
