"등촌 코인 노래방, 사장님 모르게 파헤쳐 본 진짜 속사정"

아이고, 형씨들. 내가 또 무슨 소릴 들었냐 하면은, 요즘 코인 노래방들, 특히 등촌 쪽 말이야. 그냥 동전 몇 개 넣고 신나게 노래 부르는 곳이라고 생각하면 오산이라는 거지. 겉으로 보기엔 다 똑같아 보여도, 이거 은근히 속을 들여다보면 또 다른 세상이 펼쳐진다니까. 내가 이 바닥에서 좀 굴러봤잖아? 그래서 오늘은 우리 단골 형씨들한테만 특별히, 사장님들 모르게 메뉴별 원가랑 마진율을 내가 직접 계산해 본 썰을 좀 풀어볼까 해. 뭐, 나야 그냥 노래 부르러 갔다가 호기심이 발동해서 한번 뜯어본 거지, 다른 뜻은 전혀 없다니까. 맹세해.
