U: I need a train from Cambridge on Tuesday

S: There are plenty of those! Where are you headed, and at what time?

U: I'm heading to Norwich and need to leave after 11:15 from Cambridge

S: There are 13 trains. The one that leaves closest to your requested time is the TR5949, which leaves at 11:36. Does that interest you?

U: Yes, that would be great!  I need 7 tickets, please.  Oh, and the reference number.

S: I have booked the TR5949 for 7, departing from Cambridge at 11:36 and arriving in Norwich at 12:55. Reference number: UR9DKTIK. Anything else I can help you with?

U: Yes, as a matter of fact, I also need a place to stay.

S: There are many different hotels in Cambridge, do you have an area or price range in mind?

U: Is there anything in the south with a star of 4? It doesn't have to have free parking.

S: Sure, we have two hotels for you aylesbray lodge guest house, and rosa's bed and breakfast. can I book one of these for you today?

U: Are the rooms there clean?
S: Rooms are found to be cleaned to an exceptional degree at Rosa's Bed and Breakfast while those at Aylesbray Lodge Guest House are more of a gamble, with some rooms being clean, and others not.
