I am planning a trip to Cambridge and I am looking for a train can you help out?
That's not a problem. Where will you be going to?
Stansted Airport, I will need the train to leave after 10:15 please.
Can you tell me what day you need the train and for how many people?
I need the train on Saturday and I am booking for 4 people.
The TR6310 train departs Stansted Airport for Cambridge at 10:24. Will that work for you?
That is perfect. I am also looking for a place to stay. Can you help me with that, as well?
Certainly. What part of town do you prefer?
I'm sorry, there's been a mistake. I need to book a train from cambridge to stansted airport. The train must leave after 10:15. I need four tickets.
I have a 10:40 and every hour after that. Would you like me to book it?
Yes please. Can I get the reference number for that booking? 
I can most definitely give you the reference number once the booking is complete. How many tickets would you be needing?
Like I said, I need four tickets.
Sure, I have booked four tickets for cambridge to stansted airport saturday, your reference number is YONURJSX. May I help with anything else?
I will also need a place to stay. A cheap guesthouse.
There are several guesthouses that are cheap. What area would you like it to be in?
I need it for 4 people for 2 nights starting Thursday, if that fails one night.  I don't care the area but I will need the reference number.
sorry unfortunately that is not available perhaps for another day?
Is there another cheap guesthouse available? I need it to be booked for Thursday.
I was able to do a 1 night booking at Finches Bed and Breakfast for 4 starting on Thursday. Reference number DKZG9AWZ. Any else I can assist you with?
That is everything. Thanks for the help.
You are very welcome. I am happy to help anytime. Have a wonderful day.
