RE: Never take loans from multiple sources

It is a shame for the situation that your friend is going through, I hope you can overcome your financial statement or to become aware of the problem that is being caused for the future.
What happens to your friend reminds me of situations that I have seen happen in some companies.

I have seen people use that strategy to carry some businesses, it is commonly known as: money centrifugation.

The manager issued a check to pay debts with a bad check, right on a weekend when the bank does the clearing and verification, or the manager issued the bad check when there are bank holidays commencing.

When the days passed and the check was returned, the administrator had already asked for money and paid with another check without funds to other people and used that money to pay the debt with more time.

I think that today the verification of payments is much faster and that traps scheme can never be used again, but I know that type of administrators and will have created another way of doing a new trap.
