generate response: I really can't leave at that time. Like I said, I need something that leaves after 12:30.. Intent: find_train. Slots: train-day=tuesday, train-departure=cambridge, train-destination=ely, train-leaveat=12:30
Response: My apologies. How about this: TR3420 leaves Cambridge at 13:50 and arrives in Ely at 14:07. Would this be better?
