Practical conversation
M:I can't get into my room. I mean I left my room key inside.
W:I see, sir. Those two ladies in front of your room did the same thing twenty minutes ago.
M:Oh,did they? Well, would you give us an extra key to the room?
W:I am afraid we have no extra key. So I will send somebody to your room.
M:By the way, what should I do with the key when I go out?
W:Please drop it at the front desk when you leave the hotel.
