U: I am looking for a train that departs from Peterborough and goes to Cambridge.

S: I have many trains available. What day would you like to leave?

U: We will be leaving on Sunday afternoon.

S: There are still many trains to pick from, can you narrow down a departure and arrival time frame?

U: Yes, it should leave after 20:15 and leave on monday, not sunday. Please give me a price, travel time, and arrival time for any train.

S: I have one leaving at 20:19 and arriving at 21:09. It is 13.20 pounds. Would you like me to book that for you.

U: Yes please. What is the travel time? I'll also need a hotel in the expensive price range. Can you help me with that as well?

S: Travel time is 50 minutes. I found 5 hotels you may like.  Do you have a star rating request or an area you prefer?

U: Yes, I'd like a 2 star rating and I'll need it to be in the east side of town.

S: I found one hotel that matches your criteria, It's the Express by Holiday Inn Cambridge. Would you like to book there?

U: Are the bathrooms there clean?
S: Unfortunately, the majority of guests that stayed at the Express by Holiday Inn Cambridge mentioned being displeased with the cleanliness of the bathrooms.
