U: Hello, I am looking for information on a train.

S: I can help you with that. Where are you headed?

U: I'm headed to Cambridge from the Stansted Airport.  Can you find information for Thursday please?

S: I found 19 trains what time do you want to leave the airport?

U: I need to arrive in Cambridge by 14:45 so I will need to leave in time to get there by then.

S: There is a train that leaves at 5:24.

U: That won't work, I need to arrive in Cambridge by 14:45 (2:45pm).

S: Since that won't work for you, I can get you on a train that leaves at 13:24 and will arrive by 13:52.  Would you like me to book your seat?

U: That would be just fine.  I just need the Train ID for now. I also  need a place to stay.

S: Yes, that train ID is: TR3637. Can I assist with a booking?

U: No, I don't need to book it now. Can you help me find an expensive guest house with free parking and wifi?

S: Sorry, I don't see any listings that match your search. Would you like to change price range or type?

U: Are there any in the moderate price range?

S: The Acorn Guest House is in the moderate range.

U: Do you know if they have clean rooms there?
S: The housekeeping staff at Acorn Guest House takes pride in their attention to detail as they keep rooms in immaculate condition.
