I am looking for a train departing after 11:15 from the Birmingham new street location.
There are many trains leaving after 11:15, the closet one leaving to that time will be at 11:40 and arrives at 14:23. 
Okay, I need one going to Cambridge on Tuesday.
What is your preferred arrival time?
I don't have a preferred arrival time. Could you just book me one for 13:40?
Will that be 1 ticket on the 13:40 train from birmingham new street to cambridge, then?
No, actually I'll need tickets for two people please. Oh, and can you provide the reference number when you've got it please?
Your request has been completed.  The reference number is TTH2AA7N.
Thanks. I also need an expensive restaurant serving Mediterranean food.
I have 2 results for mediterranean restaurants. One is la mimosa	in town centre. Would you like me to make you a reservation?
Sure. 2 people at 20:30 on Tuesday. Please give me the reference number.
Alright, you're all booked! The reference number is LW1N1DLA. Is there anything else I can help you with today?
Nope that should be it thank you
