Priority and Courtesy on the Course

In the absence of special rules, two-ball matches should have precedence and be entitled to pass any three or four ball match.

A single player has no standing and should give way to a match of any kind.

Any match playing a whole round is entitled to pass a match playing a shorter round.

If a match fails to keep its place on the course and loses more than one clear hole on the players in front, it should allow the match following to pass.

Consideration for other players
In the interest of all, players should play without delay.  No player should play until the players in front are out of range.  Players searching for a ball should signal the players behind them to pass as soon as it becomes apparent that the ball will not easily be found; they should not search for five minutes before doing so.  They should not continue play until the players following them have passed and are out of range.
When the play of a hole has been completed, players should immediately leave the putting green.

Behaviour during play
No one should move, talk or stand close to or directly behind the ball or the hole when a player is addressing the ball or making a stroke.
