Under no circumstances are team coaches allowed to approach the referee at half-time.
If they do, you ask them to convey all questions through their captain, but you absolutely do not discuss anything with the coach at half-time. If the coach persists the referee will EJECT the coach from the grounds. Zero tolerance approach should be applied and if the person refuses to leave the referee should request that team’s captain to assist. Failing compliance the referee may abandon the match.
