Yes, very interesting indeed ... if you threaten PeterB, he will not pay a single cent ...
And, if you remain silent and cheer his honesty and integrity, he won't do anything but promise to possibly pay you one day ....
Based on those 2 statements that PeterB had made, I guess NOBODY will ever get paid ...
Best bet is to just pursue legal action and send the guy to jail ... then his wife will probably use the "stolen" money to bail him out and to hire an attorney ...
