I know someone personally that was married to a guy that worked at Goldman Sachs. They had a circle of friends that were building contractors. They said nobody would work for Trump because he'd sign all the contracts and then refuse to pay. He'd just say "sue me."

And all the people at Goldman Sachs said that whenever Trump was in the room it was obvious he was the stupidest person in the room.

This is all anecdotal but at least it isn't made up.
