The waiter with the fruit plate went to room 406, which was at the end of the corridor. The waiter didn't notice me following him because there was a thick red carpet on the floor. I hid behind a huge vase in the hallway and watched as he took the room card out of his pocket and opened the room. The waiter went in and came out after a while. So I stopped the waiter before he saw me. "Excuse me, can you do me a favor?" I pretended to look for something. "My diamond earring is missing. Can you help me look for it? I think it might be here." "My pleasure." The waiter, wearing a red and black vest, immediately bent down to help me look for my earrings. I took the opportunity to walk over to him. As he bent down to look for it, the white corner of the room card showed up in his coat pocket.
