I'll start this by saying my best friend, and yes it was my best friend and not me, used his ATM card at the machine inside a MP. A short time later the place is busted. Several months later the FBI shows up at his work. Long story they put pressure on him to testify that he withdrew the money and what services he received at the parlor. He didn't tell me about it until it was all over. We know he could have kept his mouth shut and they would have probably gone away, but he didn't. That is not what this thread is about. It is about the mistakes made.
So what have you done that was really dumb?
