Hello, we're planning on staying in Cambridge and need lodging.  We're looking for a guesthouse which has all amenities etc.  Price is no problem.
I can help you find a nice place to stay.  First, did you have a particular area of town you were interested in?
I would really like to stay in the east of town, and preferably an expensive guesthouse if one is available.
There are no expensively priced guesthouses in that area, but there are 2 moderately priced ones and 3 cheap ones. Would one of those suit you?
Can you suggest one of the cheap ones?
I can recommend autumn house at 710 Newmarket Rd. Would you like me to book this for you?
Yes. For one person for 5 nights starting from thursday.
Booked! Reference number: WQL1WG7F.

Thank you! I also need a train that arrives by 08:45
Sure! Where will you be departing from? Would you like to depart at a certain time?
I'd like to leave from Stevenage and go to Cambridge, it should arrive by 8:45 on the same day as my hotel booking.
I have train TR1044 leaving stevenage at 7:54 and arriving in cambridge 8:43. Would you like me to book that?
No, I'm not sure I need the train yet. Thanks for the info!
You're welcome. Is there anything else I could help you with? 
No, that's all I needed. Thanks for your time!
Thank you for using our service. Have a great day.
Thanks.  I will definitely use your service again.
You're welcome.  Thank you for calling.  Good bye.
