Get into an online transaction, that goes sideways..(not hard to do)
Get all cranked up, and think about paying said person a visit..
Pay them a visit, things get heated... things get ugly..
All of a sudden you get a whole new set of problems.. MUCH more money at stake than your original loss..
Worst part about the whole deal, everyone asking you WHY oh Why did you post your intentions online...

Yupp, great way to make things better...
