I'm exhausted. Can you find me a guesthouse somewhere on the east side of town?
Sure. There are both moderate and cheap priced guesthouses in this area. Which would you prefer?
It doesn't matter, and I don't need internet access.
If you have no particular requirements, you might like the Autumn House, which is an inexpensive 4 star guest house on the East side.
Does it include free internet?
Yes it does.
I want to book it for one person, four nights starting on Sunday. 
You can rest now, your reference number is BQ8VSRRZ. Is there anything else I can assist you with today?
I can't rest yet.  I still need a train.  I am traveling from Cambridge to London liverpool street.  Can you help me out?
Absolutely.  First, I need a few more details.  What day will you be traveling?
I'd need to leave on thursday and arrive by 14:30. 
There are 5 trains that meet those requirements.  TR5504 would have you arrive by 13:27.  Can I help you buy a ticket?
Yes please for one. I will also need a reference number.
Booking was successful. Reference number: 9COW8ZI5. Is there anything else I can help you with? 
No, that is all, thank you. 
Fantastic! Have a good day.
