I need a train that leaves after 13:30 saturday afternoon please. 
Can you please tell me what your destination is for that trip?
I would like to depart from Cambridge and arrive at Stevenage, please.
There are 5 trains meeting that criteria. Would you like me to book you a ticket?
Yes, I would like to book the ticket now, could I please have the train ID? 
The train ID is TR8813, how many tickets would you like to book?
I can take care of that myself. Can you also help me find a place to dine in the south, priced cheaply please. 
How about Portuguese cuisine at Nandos? Would you like any more information about them or assistance booking a reservation?
That's perfect. I'd like to book that restaurant for just myself at 10:00 on the same day. Could I get the reference number as well, please?
OK, you have a table for 1 at 10:00 on Saturday at Nandos. Your reference number is 3JRN2T9Y. Can I help with anything else today?
I am all set. Thanks!
