Common courtesy, decorum and a prevailing sense of personal responsibility are lost in these frothy times of high demand and inflated economy (i.e. the fast train to DoucheVille). But one day this economy is going to correct in earnest and all these allusions of grandeur are going to give way to some harsh realities. Being too-cool-to-act-professional is going to make a lot of mustaches sad.
Effective smart people are humble and kind (like Matz). Blowhards are insufferable douchebags and no amount of fake rebellion against 'professionalism' is ever going the change that.
