Loan Pay Back...might be a bad sign! Even if they had the money sitting around, it might have been a better idea to keep it for cash flow. The fact that they wanted their money back could possibly mean they are more aware that now is the only time they would get it.
All I am trying to say is if they had lots of work on the table they would not have been so scared to lose their money.
Afterall, we will never know what they know!
