U: I need to book a train Friday to London.

S: First I need your departure and the times you want to leave or arrive.

U: I believe I was in error. I need a hotel in the centre with 4 stars.

S: There is the university arms hotel in the expensive price range that has 4 stars would you like me to book that for me?

U: I need a place with a really clean bathroom. Will this hotel fit that description?
S: I found two reviews that talk about how clean the bathrooms are, and one that said the bathroom was a bit dirty. Would you like to book a room there?
