generate response: I'm going from Cambridge to Broxbourne, departing after 20:45 on Friday.. Intent: find_train. Slots: train-day=friday, train-departure=cambridge, train-destination=broxbourne, train-leaveat=20:45
Response: The first train after that time is TR8966. It leaves at 21:01 and arrives in Broxbourne at 22:01. Would that work or do you prefer a later train?
