Atleast when a fight is not made you've not dished out money unlike paying then watching some ***** quit because his shoulder is hurting him a little bit.
it all depends on the circumstances. I felt that Alexander quitting against Bradley was really bad, but I can understand Cotto quitting against Margo. Meanwhile you got Povetkin bitching out of the Wlad fight which is unacceptable, but sometimes it's normal that two fighters can't come to a deal.
