You would be at turns amused, baffled and disgusted at all the petty backstabbing and one-ups-manship that is common in the bureaucracy.

School custodians, lunch ladies and secretaries never miss an opportunity to exercise a little sadistic power over children, parents and teachers. Ignoring the bad behavior doesn’t make it go away, much the same way ignoring a bully tends to empower them.
