Fairness, with all due respect is a bunch of polony!

Just like when someone says with all due respect - know that the next line to come out of their mouth is probably going to be something disrespectful.

Similarly, When a person says that it's only fair...

Or I think that that is fair...

Know that it probably isn't fair.

Fairness is such a subjective thing. 

Your employer probably thinks he is paying you a "fair" wage. And let's face it, he probably isn't. 

You probably think you put in a decent day's labour. And I would bet that your employer would probably disagree with you.

The next time you make a deal with someone don't look for what is fair, seek to be generous.

Generosity. That is the difference between abundance and scarcity.
