What’s the probable occupation of the woman?

W: Good morning, sir.
M: Good morning. I wonder if you can help me. I have lost my wallet.
W: Where did you lose it, sir?
M: Mm, I remember I left it on the table in this hall last night.
W: Can you describe it, sir?
M: Yeah. It’s a small wallet. Black feather. In it, there’s a picture of my son and about 600 dollars. By the way, there’s also my ID card.
W: Let me see. I’m sorry, but I’m afraid we haven’t got anything like that, sir.
M: Well. If there’s any information about my wallet, could you please tell me? My name is William White. I live in Room 1012 of this hotel.
W: No problem. We’ll inform you as soon as we have any news.
M: Thank you so much.
W: With pleasure.
