 {'role': 'USR', 'utterance': 'I am sorry to hear about that. Would you mind coming with me to my office and tell me exactly what happened here?'}
 {'role': 'SYS', 'utterance': 'Of course not.'}
 {'role': 'USR', 'utterance': "Are you sure that it isn't somewhere in your room?"}
 {'role': 'SYS', 'utterance': "Yes, I've looked everywhere in my room and I can't find it."}
 {'role': 'USR', 'utterance': 'Ok, when and where did you last see it?'}
 {'role': 'SYS', 'utterance': 'Last night on the dresser. I took it off before I went to the shower, and forgot to put it back on after the shower. And this morning I left the hotel in a hurry without wearing it.'}
 {'role': 'USR', 'utterance': "Are you sure you didn't wear it this morning?"}
 {'role': 'SYS', 'utterance': 'Yes, I am positive.'}
 {'role': 'USR', 'utterance': 'Did you remember to lock your door before you left then?'}
 {'role': 'SYS', 'utterance': 'Yes, I think I did. It has to be one of your maids who took it. I want my necklace back.'}
 {'role': 'USR', 'utterance': "Well, I understand how you feel, and we will try to do our best to help you. But first please allow me to send one of the housemaids to your room to look for it again thoroughly, just in case it's still in there. If she finds it, we will all be happy. If she doesn't, we will turn the whole matter to the police. But I must say that the hotel can't be held responsible for your loss. You should have locked your gold necklace away at the hotel's safety box. If you had read your key card carefully, you would have realized that we specially warned you to do so."}]
{'role': 'SYS', 'utterance': "That just isn't good enough. Cet me your general manager. I want to speak to him now."}
