I need to find a train that departs from Cambridge and arrives by 9:15. Can you help?
What is your destination? 
I'm traveling to Ely.
We can definitely help you with that, I just need to know the day you will be traveling. 
For today, arriving by 21:15.
I'm sorry, I need to know the day you will be traveling.
I am departing on Sunday. 
I have a train on Sunday that arrives at 20:07. Would that do?
That's perfect.  Could you book it for 8 people? 
Booking was successful, the total fee is 28.16 GBP payable at the station . Reference number is : LZLSJZ1K. Anything else I can help with? 
Thank you! Will you please find me an expensive restaurant in the Centre part of town?
Would you like me to book it for you ?
no booking yet for the restaurant.  I want to eat at a restaurant that serves thai food.  Do you have any?
Bangkok City serves Thai food, and is in the centre part of town. Would you like me to book it for you?
Yes please, for 8 people at 11:00 on Sunday.
What day would you like to book the table for?
I just told you! sunday! Now please go on and book and send me the reference number 
It seems that I can not reserve that at the moment. Would you like me to try a different restaurant?
How about at 10:00 instead?
I will book your reservation for 10:00 on Sunday.
OK, please do that and get me the reference number.
Booked! The table will be reserved for 15 minutes.
