Hi there, I'm trying to book a train for Saturday that leaves after 18:45. 
I can book tickets that leave london kings cross that leaves at 19:17?
No, I don't really want to go there. I'd like to go to London Liverpool Street.
I have one leaving at 19:59, if that's acceptable?
Can I get the travel time and train ID?
It is train train TR2166 and the travel time is 88 minutes. Would you like me to book your ticket?
Not just yet. Can you find me a place to dine in the south? Moderate pricing please.
There are two restaurants, would you like italian or modern european?
Ooh, modern european sounds interesting. What have you got?
The european restaurant is restaurant alimentum.  Would you like me to make a reservation?
Yes I would like a reservation for 6 people at 10:45 on saturday please. 
Unfortunately, they do not have availability at that time. Would you like to try another time? 
Try 9:45 then, please.
That time will not be available. They are closed then.
I'm sorry, before we book the restaurant.. can you make sure the train is departing from Cambridge, please?
Yes, that train is departing from Cambridge.
Are you sure they are closed at 9:45? Is there a different european restaurant in that area available at that time?
No, sorry, that restaurant is the only european restaurant in the area.
Can you book that for 6 people at 09:45 on saturday?
Unfortunately, there are no tables available at that time. Would you like to try another time or day?
How about 9:45 instead?
Unfortunately, there are no tables at 9:45. Try requesting a NEW time or day.
Why don't you just schedule it and give me the reference number please I know they are very busy this time of year.
I am sorry but I need for you to specify a date and time please.
Can you try 10:45 on Saturday again? Maybe there was a cancellation.
I'm sorry, again, that time is not available.
Okay. Thanks anyway. Good bye!
You are welcome. Sorry we were unable to book the table for you. Please call back if we can help with anything else.
