I've even heard the excuse from one or more of the non-pay jokers that
I hadn't lost anything if they didn't pay me, because I never had it in the
first place.  You can bet  ysa (your sweet _aa) I will never do work for
them again, and any degree of bad rating is less than they deserve.  I view
the negative ratings system as a way of warning others who they may desire
to take advantage of.
