U: Hello, I need a train to take me to Kings Lynn and I really need to arrive by 10:30. Can you help me?

S: Absolutely! Where are you departing from?

U: I'll be leaving from Cambridge on Thursday.

S: I have train TR1855 that will get you there at 9:58, would you like me to book a ticket?

U: No, but could you tell me the price?

S: that should cost you 9.80 pounds

U: Okay, thank you.  I would also like to get info on a  hotel called City Centre North B and B.

S: Its a relatively cheap guesthouse on the North side that offers internet and parking

U: Comfortable sleep is important to me, can you make sure I get a very comfortable mattress?
S: The City Centre North B and B has really negative reviews about their beds. I suggest we look at another hotel.
