The service industry offers its workers a myriad of shitty experiences: Terrible customers, terrible employers, terrible coworkers, and an (often) unpredictable income that relies upon strangers' ethics and understanding of their social obligations.

It's ever a wonder how people like this manage to get into positions of power over other people. Unfortunately, it's often probably because the organization they're working for is run by toxic, cruel people who recognize the toxic and cruel (or spineless, subservient) traits in those they promote to management positions within their business.
