Since you wanted anecdotal stories, I've known multiple relatively successful people (not billionaires, but millionaires who moved in high powered social circles) who didn't read the contracts for their rental cars or hotel rooms. It's not a particularly interesting anecdote. The anecdotes aren't interesting. Nothing ever came of not reading the contracts, but they were successful people who didn't take ten minutes to read a contract.
