Where does the conversation happen?

M: Will you do me a favor, miss? I must get up earlier tomorrow. I want to go to the seashore to enjoy the morning scenery here; you know this is my first visit to Miami.
W: Yes, sir. You can ask for the wake-up calling. And what time do you want me to call you, sir?
M: At half to six tomorrow morning, please. And tell the operator to call me by phone.
W: OK, sir. Good night. Have a good sleep.
