After reading the Quora post about getting into an event and playing ping-pong without paying I wasn't too impressed.

The rules would be more strictly enforced if more people tried breaking them or the pay-off from each breaking was bigger. He just found a few rules in which neither incentive to enforce was big enough. No big deal.

So the examples (a white guy attempted to cut a line and failed) are really weak, I'm sure there are bigger issues for minorities than this.
