A chicken head being processed is a case of either the workers not caring or laziness, but there has to be something else going on besides not caring and laziness when a human finger gets through the process.
At a chicken processing plant, there are bound to be heads of chickens around, so it would make perfect sense if one accidentally got into the mix, but what factory has human fingers laying around??? It obviosuly came from a worker, and there lies the mystery...
Imagine if someone at your workplace lost a finger, do you really think that day would be considered a "normal" day? Do you think the incident would go by unnoticed? Do you think the person (who lost the finger) would be able to hide it? Do you think the other employees would act as if nothing has happened (and went on about their job duties)?
I can see how the finger can get "through" the process unseen, but where I get confused is how it can get "into" the process to begin with.
