Why do you have to put the flag back into the golf hole neatly, in accordance with the correct behavior in golf?
After completing a golf hole, it is important to put the flag back into the hole neatly and accurately. Otherwise there is a risk that the flag will fall out of the hole due to a gust of wind or similar and subsequent players will no longer be able to recognize the flag in the golf hole. A flag that is not stuck vertically in the hole would also have a disturbing effect on the visual appearance and the assessment of the distance for following groups of players.
In addition, should a player manage to hit the golf ball from outside the green in such a way that it rolls towards the hole or directly into the hole, there is a risk that a flag that is at an angle or not correctly positioned in the golf hole would prevent the ball from going in. It does not matter whether the player is far away from the green or relatively close to it.
