I accepted an exploding offer. It was a harbinger to a larger detonation. There's a simple way of looking at this type of behavior: If someone is willing to go negative on you at the beginning (evidenced by 'denying' you an investment because you didn't take it when they wanted you to take it) then you should assume they will be willing to go negative on something else of a similar or greater magnitude at a later date.
