When experts say there's no point in complaining to the referee because he won't change his decision, it's not entirely true. If it's the 1982 World Cup and you're a Kuwaiti FA official (who's also the brother of the Kuwaiti emir) things are different. France scored to go 4-1 up but the Kuwait team claimed they stopped playing because of a whistle in the crowd. The president of the Kuwait FA came down from the crowd and threatened to remove his players. The Soviet referee amazingly took the goal away. Yeah, he wasn't invited back.
