U: i'm looking for a train leaving on thursday and arriving by 11:45

S: There is a train leaving Thursday from Kings Lynn at 10:11, arriving at Cambridge at 10:58. Would you like me to pull up other listings?

U: Can you look up trains departing from Broxbourne instead?

S: I would recommend TR0393 which leaves Broxbourne at 5:32 and arrives in Cambridge at 6:32.

U: Great!  Can you book 2 seats for me on that one?

S: Your train has been booked. Your total cost is 35.79, payable at the station. Your reference number is SQUCLNLA.  Can I help with anything else?

U: I need to book a room in a guesthouse that has free parking.

S: There are 21 guesthouses in town with free parking. Do you prefer a specific area of town or do you have a price range?

U: Not really but I do need a 4 star rating.

S: Do you have a price range in mind? And will you need wifi?

U: WiFi is not necessary, but I would like free parking. I'm looking for mid range pricing.

S: There are nine moderately priced guesthouses available. I suggest Home From Home, a 4-star guesthouse that comes with internet and parking. Would you like to book a room?

U: Is the bed comfortable, because that is what I need?
S: Reviews of the beds are mixed, so if that's important to you, it may not be a good choice. Would you like another option?
