[user] can you tell me the station where the bus will arrive, and also the name of the station from where the bus will leave? [system] the bus will depart from pacific central station, and it will arrive at king street station. [user] is there some other bus you can suggest, in case i need economy extra tickets? [system] how would you like having economy extra ticket for the bus which leaves 8:10 am, and has the ticket price as $40? [user] that seems nice. that would be all.
