Sure, in this case the bribing rule may be okay since they are all standing in line at an expensive restaurant and presumably could afford the $50 bribe. What if the rules were made public and now everyone starts to bribe the maitre d'? Imagine what that would do :)

Although the book focuses on competitive video games it quickly establishes an important point that can be applied to nearly every situation in life: There are two types of people in a situation, "scrubs" who make up a subset of rules for the 'game' they are playing and those who understand the true extent of the rules.

One view I hold as a result of this thinking is my strong support for financial regulation. I was depressed to see so many people pointing fingers at wall street and talking about them being so immoral and corrupt. What they did was extremely damaging to society as a whole, but their motivation lies in winning their 'game' which is the money acquisition objective; and they pushed to the very border of what the rules were. Those playing the game came out very successfully; society may be crumbling around them, but they have their huge bonuses. Going angry-mob on someone for successfully achieving their objectives is just being a scrub. Most people talk about how they violated rules that don't exist: imaginary rules hiding behind noble sounding words like ethics or morality.

While the scenario can be depressing looking at it that way, it ultimately is accepting reality for what it is. This is how you can chart a path to actually deal with the issue; if you don't like the way the game is played, you have to change the rules.

But in my personal life it generally has a much more positive theme to it. I learn the rules of what is valued at my company; how much depends on social behavior and how much on productive output. I learn the rules of social interactions at parties and clubs; and adjust my behavior to maximize my gains. Even on Hacker News I learn the rules of what is acceptable as a quality comment, and what is not. I think this comment will get upvoted. It adheres to the values of adding to the discussion and providing new information... along with the always popular "personal advancment" story.

It's funny to me now seeing how many people fail at various 'games' in life simply due to not understanding the rules of the games. They fight against it, like a fish swimming upstream. If you don't even understand the rules of the game, how are you supposed to gain skill at it?

edit: Just to clarify, when I talk about the rules binding things like the financial system I do not mean the regulations alone (which may be broken through corruption as others have pointed out). Those rules are actually a subset; viewing them as absolute is scrub-talk. I am talking about the REAL rules of the game which includes 'shady' things like bribery.
