Wow.
Leaving aside 3, 5, and 7, which is largely just incompetence, you seem to have a curse similar to Mary Anne's. Mary Anne has the ability to attract fundamentalist religious psycho hose beasts from clear across the state. Maybe you have the same problem with lousy businessmen.
I have run across guys who made stupid mistakes and wasted money, but never to the extent you have, and I have never run into a real crook at any of my businesses.
