Ref's and training

In all fairness most games are called fairly, however every now and then you get a REF who either has issues with a coach or the team is one of his family favs or his son or daughter played on the team and the coach is his friend, (you get the meaning)
So then the game is not called fairly, as in the game today on field 2 at Cherry Island. The Ref would warn the green team and talk to them however for the same exact thing he would yellow card the other team.
That is not how a REF should call a game, if he cannot call it fairly then maybe he should be removed from the CENTER..
The green team kicked the ball out of bounds and almost to the snack bar and the REF said green team do not go get that ball and he took the ball from the goalie from the yellow team so the very next kick the goalie from that other team had to go and chase that ball since the REF told the green team not to go and get the ball that they kicked out.. (not making since, so who was going to get that ball? we did after a few mins, however the REF should have never of did that, since the yellow team had to chase every ball that was kicked out and the REF never told them not to go and get it like he did the green team)
Then in the middle of a good play(ball going good and moving down the line, yellow team has the advantage) the REF blows his whistle and yells at two boys that did not even have the ball or was even in the line of play? Then he took the advantage away from the YELLOW team and made them do a drop ball?
This game was not called fairly, however it is to late now and thanks to the REF who took the greens side the BOYS were almost at blows with each other... the Green teams COACH refused to shake the yellow teams hands and once again due to a POOR CENTER REF a game was not called fairly....
It makes you wonder if the game was called fairly would the green team of had the advantage? I do not think so.
The Ref was critized by both sides for his not being fair to both teams and that he did a poor job and should be ashamed of himself, he said THANK you and kept walking,
it was also getting dark so in all fairness to all players the game should of not be played on unless there were lights...
At this point it really does not matter who won or not that is not what this posting is about..
REf's are trained and recertified each year and the Ref Coordinators are at each game and are supposed to be watching the REF's as the Center to see what more training they need.
Each game is different and has to be called consistnatly.
