These are here just to give you some guidelines on how to act at the shooting line so you do not annoy your fellow archers so they do not a) thump you or b) shoot you.
This is especially important at competitions but will also help at normal sessions.

A Good Archer:
(a) Does not talk in a loud voice whilst others are shooting.
(b) Does not talk to another competitor who obviously prefers to be silent.
(c) Does not make any exclamation on the shooting line that might disconcert a neighbour
in the act of shooting.
(d) Does not go behind the target to retrieve his arrows before his score has been
recorded.
(e) Does not walk up and down the shooting line comparing scores.
(f) Does not touch anyone else’s equipment without permission.
(g) Does not leave litter.
(h) When calling scores does so in groups of three, for example ‘7 – 7 – 5’ pause ‘5 – 5 – 3’.
(j) If he breaks another’s arrow through his own carelessness, offers to pay for the arrow*
(k) Thanks the Target Captain at the end of each round for work on his behalf.

(taken from GNAS “Rules of Shooting”)

* Damage caused during the course of an end (Robin Hood, Arrows dented etc) by your arrows do not count as being damaged from carelessness, however, it is common decency to offer to replace a damaged shaft
