When someone spends a big amount in your bazaar they usually try to mug you and take away a great deal of that money back from you. With the new mugging system they put in place it is a very affective way to get a lot of the money back. I think they should change it to where you can blacklist they players that you think are up to no good. So, that they cant buy items from your bazaar and turn around and steal your hard earned torn dollars.
Or they could make the amount of money the player spent on your baazar into a cashiers check and stored in the bank for 24 hours. That way no one could take back part of the money they just gave you.
