I see hanging in the store windows signs that read "Treat our employees like garbage and receive special discounts!" With mine own eyes I have seen it.
Think of that the next time you hear news about a serial killer that hates his own people with such ferocity. They have their reward.
P.S. My girlfriend told me she didn't get it so I'll elaborate. I've seen first hand that people who scream obscenities towards customer service types and the like are generally rewarded for it. What many refuse to see is that those on the receiving end become angered by it, on the job they must hide such anger, but it's there. Over time that anger builds and in some cases results in a very violent release. The killer is jailed while those who created the killer are rewarded. Nonetheless those who created the killer still have to deal with the killer's presence and such is their true reward.
Today many say there is something wrong with the killer, that maybe he was just born that way. I believe this is incorrect, there is something wrong with the system that created the killer.
