I once turned down a job because they said they would pay for the move but i had to pack myself....turned it down as it indicated to me previews of coming attractions.
As it turned out I started my own business instead and earn 3 times what the salary with them would have been.
I once turned one down because in the middle of my interview the owner of the company took a telephone call from his wife.
He was so nasty, loud, and condescending to her, I decided immediately that I would not work for this guy for all the tea in China.
