Beauty and the Beholder

Different cultures certainly have different standards when it comes to appreciating what is right and what is wrong; what is permitted and what is not; what is beautiful and what is not; what is music and what is noise; etc.  This man spray painting metal hose reels on a public sidewalk would be arrested in many countries.  In Cambodia it doesn’t rate a notice.  And if someone challenged the idea, the probable response would be “Floors/sidewalks are SUPPOSED to be dirty/messy/etc.” so what is the problem?
