THINK ABOUT IT. JUST THINK:
All those people, on their laptops, doing work. The shops give off the image of being a chill and relaxed environment. Smooth jazz, friendly baristas, nice decor. But it is filled with worker bees being served a drug, yes a DRUG, so that they can work more efficiently. Coffee shops represent the man who puts a smile on his face and says "what a great day it is" without even knowing what makes him happy, when in reality he is drinking mad cups of espresso to kiss his boss's ass with that laptop he has in his satchel.
Also, guys wear scarves there.
