Unit 13 I've left my key in my room.

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.
