You will need to decide if the player’s behavior is bad enough to call. Short of that, it is something you, your group, and/or other players will have to work out with them. If the behavior is bad enough, or there’s a pattern of it for that player, you can notify the TD and/or the PDGA Disciplinary Committee.
