AOA's Mina revealed she was rude to the FNC Entertainment head while she was drunk. 

 
On the June 7th episode of 'Kim Shin Young's Noon Song of Hope', DJ Kim Shin Young asked her, "I heard you spoke informally to your agency head after having a drink?" Mina shared, "It was a few years ago, and it's still a big deal. It was kind of traumatizing."

She revealed the FNC Entertainment head Han Sung Ho had drunkenly said after an AOA concert, "I'm going through a rough time, Mina." Mina must've been somewhat miffed by his complaint as she responded, "Ah, you think you're the only one? We're more tired than you."

Mina continued, "Hongki oppa and the other sunbaes were there too. Thankfully, the label head doesn't remember it completely." Kim Shin Young advised, "Just say you never said it."
