As free daily newspapers became famous in Korea, a blue ocean was created by people who began to collect these newspapers inside the subways. This is where the controversy begins. Some citizens say these people are like crocodile birds who clean up the left behind papers from the racks. Others are displeased with these people because they often have bad body odor and push people away to get the newspapers. A solution which might satisfy both sides of this argument is necessary as civil appeals against these people are increasing.
