{'service': 'train', 'act': 'inform', 'slot_name': 'arrive', 'value': '20:44'} {'service': 'train', 'act': 'inform', 'slot_name': 'choice', 'value': 'a few'} {'service': 'train', 'act': 'inform', 'slot_name': 'leave', 'value': '18:01'} {'service': 'train', 'act': 'inform', 'slot_name': 'id', 'value': 'tr1766'}
