U: I need a train going to London Liverpool street and leaving after 17:00.

S: There are plenty of trains going to london liverpool street. Which city will you be departing from?

U: Cambridge on Wednesday.

S: There are 4 to choose from. The first one after 17:00 would be the TR4757, leaving Cambridge at 17:59 and arriving in London, Liverpool Street at 19:27. Would that do?

U: Yes, that would work well. Can you book it for 5 people and give me the reference number, please?

S: Sure, it is all set.  The reference number is HEDQCGXW and the total fee is 83 GBP payable at the station.

U: I'm also looking for a cheap hotel. Can you help?

S: Sure, there are 9 cheap guesthouses and one hotel that fall in the cheap price range. Got a area of town you want to stay in?

U: Are any of those 2-star rated?

S: None of them has a 2 star rating. The ratings are either 0 stars of 4 stars. Is there an area you prefer?

U: How about an expensive price range?

S: There is one expensive 2 star hotel. It is Express by Holiday Inn Cambridge and is located in the east. Would you like me to book it for you?

U: Do you know if the hotel has a comfortable bed?
S: Express by Holiday Inn has really comfortable beds according to one customer, but that was the only review I could find.
