Mr. P.

Mr. P is concentrated. There's great professional pride in his quick movements. On the 20th floor he takes the tray and balance it on his left hand's fingertips. In a fast pace he reaches the room and knocks on the door with his right hand. With a melody put into the words he says: "Room service".
Mr. P has been delivering room service for 20 years at the same hotel.
This is his story.
