I would also advise to anyone to be super friendly on your way out and do it professionally and properly. Even if you change industries or leave the country. The world is a very small place, especially in the digital age. There is nothing to be gained by being nasty leaving, aside from some short term satisfaction. You will not just alienate your boss and his peers, it will also affect your coworkers who have to stay behind. For example if people do not give decent notice, it will only be taken out on the backs of their coworkers. The boss sure won't be the one picking up the work left behind or doing the training that could have been achieved in the 2 week notice period.

A lot of people think their boss is an idiot. But usually the manager knows why someone leaves and if there was friction, they know it is what was ultimately the issue. It does not have to be brought up and it will achieve nothing if it is.
