hi . i am looking for a train going to kings lynn on monday . i would definitely like to arrive by 14:45 at the latest .
i have 19 different options . can you tell me if you have a time you want to leave or arrive by ?
{'service': 'train', 'act': 'inform', 'slot_name': 'choice', 'value': '9'} {'service': 'train', 'act': 'request', 'slot_name': 'leave', 'value': '?'}
there are 9 possible trains to take , do you have a preference on departure time ?
