NOW Have We Heard It All?

Hanh mitakuyapi.
Recently, I was sent to work for a local window-manufacturing concern on a temp-to-hire assignment. On my second day, I told someone that I have a college degree. (Strike 1) They asked "in what?" and I replied, "Chemistry". (Strike 2, and possibly, 3. Read on, and you decide.)
This person then asked, "Then why are you working at a job like this?" and I replied, "I was in heart research for 9-1/2 years and decided that was enough. I had a small-jobs contracting and property-maintenance business for 20-some years; but when my man died during a mugging, I didn't have the energy to push a business any more. No one wants to hire me permanently so far because they figure I'll quit and go back to business, so I work temp. I have bills to pay, same as anyone else, after all."
One of the office people heard this exchange and suddenly, the plant manager acted as if I had Grand Mung and the assistant plant manager acted as if he were so0o sad for me and them, and the HR guy acted as if he wished he could be friendly but he "had to be careful"...
Are we all wondering "what's really going on here?" (The third of my Four Favorite Questions, I note..) I expect we are.
Eventually, I got someone to spill the beans about the sudden change of attitude.
It seems the company has a patent for its window-making process. Patents being expensive and North Dakota being part of the Land of Backward, the "brains" in the front offices "thought" that since I have a degree in a hard science, and especially since I already knew how to build a window (it isn't rocket science, takoszja..), I was in a position where I could easily steal their patent and their market. "I know too much."
If this isn't duh-uh thinking, I don't know what is. But I can't help wonder if now we haven't heard everything..
I feel no great sense of loss here, though.. Production can be very, very bor-ing, and this job was.
More importantly, though, is their attitude that "everyone is a thief at heart but them". Or maybe, that "everyone is thief at heart, including them, so they 'must' go to extremes to protect their investment". While it is true that it's only paranoia if someone isn't out to get you, I find their perspective offensive.
Whichever - I don't want to work for anyone with an attitude like that, so I spent last week chopping onions in a food-processing plant or cleaning in a school district, and one day kneeling on a folded towel, cleaning vomit off the floors of an elderly friend's house with a putty knife, before I scrubbed them with bleach and Spic-n-Span, because she has The Ultimate Vile Flu which is currently coursing through this area (1400 cases and counting; it can put you on the bedroom-to-bathroom trail for up to a week!), and she was too weak to get to her bathroom in time, and therefore of course too weak to clean her floors, poor thing..
All of which were more interesting jobs than making windows for the silly group with their patent-and-thieves-in-every-corner fantasies.
Let's hope my angel-of-mercy activities are rewarded with my not getting TUVFlu.. I live alone, too.. and then perhaps we can find me either the last $1500 I need to get my tiny company back in the market, or a real job so I can save up the $1500 and get my tiny company back in the market - no paranoid fantasies. Mitakuye oiasin.
