Entertainment company CEOs are known to be tough on their trainees and artists, but FNC Entertainment's president may be one of the toughest ones yet.

The members of AOA guested on SBS' 'Choi Hwa Jung's Power Time', where DJ Choi Hwa Jung mentioned, "Your CEO's discriminatory treatment is (in)famous." The members admitted, "It's only now our CEO knows our names." ChoA said, "It's because our group has so many members."

Choi Hwa Jung asked what their CEO called them before he memorized their names. The AOA members said he called them 'nicknames' from their first impressions at their auditions. Mina said, "I was a shopping model before so I was called 'shopping mall'." Yuna said, "I played the keyboard and sang at my audition. So I was called 'keyboard playing child'." Maknae Chanmi was simply called 'maknae', and Hyejeong, who had once been a cheerleader, was called 'cheerleader.'
