And while a referee can read all the books and take all the courses on officiating in the world, the best way to improve is practice. According to Demo, officiating is a continuous learning process and there is no substitute for experience and the confidence that comes with it. You have to practice, do as many games as you can and decide what you need to work on. You can learn at every level. As for the spectators, Demo says it's best to just ignore them.
Fans can be pretty biased.
They pay to come watch and everyone wants to root for the home team. You have to back each other up. An easy job officiating is not, yet most referee's would tell you how much they enjoy it. Not that many of us are power hungry mongrels. That said, it is a referee's job to maintain control of the game.
