when you go and cash/deposit a check, the bank pretty much gives you the money right away and doesn't know that the check will bounce for a couple days.
After they find it bounces, they go after you for the money.
so you cash the 15k send back the 7.4 or whatever, but are stuck with a 15k debt to the bank and whatever bank fees come with bounced checks.
That's how I understand it to be anyway.
