Two men are playing a game in a corridor

Two men are playing a game in a corridor. One man, wearing a blue t-shirt, jeans, and a cap, throws a small yellow ball, then bends over backward as the other man, wearing a black shirt and pants, catches it. The man in the blue shirt then jumps as if startled. People are standing in the background beyond a doorway. The corridor has a grey floor, concrete walls, exposed pipes, and whiteboards covered in writing. An elevator is visible to the left.
