[{'role': 'USR', 'utterance': "Hello, I work for Sunny Tour Holidays. And I'm interviewing people about their Holidays. Would you mind answering a few questions for our survey?"}
 {'role': 'SYS', 'utterance': 'No, not at all.'}
 {'role': 'USR', 'utterance': 'Thanks a lot. First, could you tell me about travel arrangements for your last holidays? Did you experience any difficulties in your journey?'}
 {'role': 'SYS', 'utterance': "Well, our plane didn't take off on time. It was delayed 5 hours. So we didn't get to Lhasa until 4:00 in the morning, and we were very tired when we got there. But we managed to book a car at the airport through a car rental platform. And it dropped us off at the hotel in time around 7:00 o'clock for breakfast, so that was alright."}
 {'role': 'USR', 'utterance': 'And how was the hotel?'}]
{'role': 'SYS', 'utterance': 'Well, we were a little disappointed with the room, but the Patella Palace was just a stone thrown away.'}
