You know the worst thing about working in an office that no-one thinks about...
... I came on here to write this but also saw Sadpunk's thread.
So without wanting to repeat stuff, the main issue with working in a regular office is that it's a building full of underachievers with broken dreams.
No one chooses to be in one of these hellholes. No one dreams of become a middle manager in an office so everyone is pretty pissed off about it. Whether they know it or not.
Welcome to the fail train.
