I look at bad ref decisions as annoying at the time, but over a season or two, they do tend to average out, what offside goal for you this week, goes against you next week. I know somebody who is a ref and he says, they don't like bad days at the office, when they get things wrong, but they are human and fallible.
Unfortunately, simulation, seems to a a bad habit that has appeared much more in the premiership along with more Latin players. It is something I hate and when supporting my team, if they win through this it leaves a very bad taste in my month where they have won through cheating.
I'm convinced that the FA, UEFA and FIFA don't want electronic aids for better decisions as they want to keep football controversial and constantly in the news and in pub discussions and hence through this, make it have a higher profile so they make more money.
I enjoy watching a game of football, but I can take it of leave it and would hate to be a fanatic that has to go to every match, where I know several people like this, where their life totally revolves around football and it is hard on the rest of the members of the family, well until they end up divorced it is.
