What is the umpire's responsibility regarding spectators during a match?

The umpire's responsibility regarding spectators is to ensure they do not disturb the players and remain clear of the greens. This responsibility is crucial in maintaining the integrity and focus of the game. Spectators can inadvertently distract players, affecting their performance. By ensuring that spectators are positioned appropriately, the umpire helps to create an environment that allows for fair play and concentration.

Allowing spectators to stand anywhere around the rink could lead to interruptions or distractions for the players, thus compromising the quality of the competition. Encouraging interaction between players and spectators could also lead to disruptions, detracting from the game. While managing crowd noise is important, asking spectators to leave for cheering too loudly might be excessive; it's more important to ensure they are generally respectful and considerate of the match atmosphere.
