I am looking for a train going to Cambridge.
Great and welcome! How about friday at 05:17? Is that time acceptable?
yes, that is perfect.
It will cost 23.50 pounds and the travel time will be 51 minutes, would you like to book it?
Yes, please.  Two tickets. 
I've booked you 2 tickets on train TR5219 from london kings cross to cambridge on friday. The total fee is 47.2 pounds and your reference number is DVRX2C6V.
Thanks. A friend told me about a restaurant called the rice boat. Do you know it?
I have not been myself but hear it is nice.  It serves Indian food on the west end of town.  Would you like me reserve a table for you?
Yes please, 2 people at 20:30 on sunday.  Can I also get a reference number?
I was able to book that table for you (Ref #UU2PWIV7). Can I help you with anything else today?
Nope, that takes care of everything. Thank you! 
You're welcome! Have a great trip!
