I read this from The Repossession Mambo by Eric Garcia:
No one is a Bio-Repo man by birth, no matter what the commercials and billboards say. And that slogan -- "Help The World Help Themselves." Eech. They make it sound like everyone's born to play the part of a killer, but that's not so. Like any other artistic endeavor, it can be learned. Some have a natural talent, of course, and some, like Tony Park, take to it a bit too easily, but there are nuances and techniques to the job that could fill the largest of instruction manuals.
There are three expressions that confuse me:
1. What does "eech" mean?
2. What does "take to it too easily" mean?
3. What does "fill" in the last sentence mean? Is this sentence saying that the insturction manuals tell you all those nuances and techniques a repo man needs to know?
