Where does the conversation probably take place?

M:  Hello. I’d like this guidebook,  please. How much is it?
W:   All things are free here.
M:  Oh,  thanks. I’ll stay in the city for one week. Could you tell me what places I should visit?
W:  Well,  there are a lot. Are you interested in islands,  such as Lantau?
M:  Islands?
W:   Yes. There are a lot of interesting things you can see—old villages and churches. And the scenery is beautiful. Take this booklet. It tells you more.
M:   Thank you very much. That’s a great suggestion.
W: You are welcome.
