S: From where to where?

U: I'm leaving from London Liverpool Street and I need to arrive in Cambridge by 09:30.

S: the TR2503 will get you to your destination at 9:07.

U: Perfect. Can you book that for me for 3 people?

U: I also need a hotel in the East.

S: Do you need parking at the hotel?

U: It doesn't matter, but I do need free wifi and the hotel should have a star of 4.

S: Which price range would you like?

U: I'm open to different price ranges. What is available?
