My pet peeve about LMF

[minkyung]

I remember a gym instructor. He has many customers, rich ones. So, he has lots of money. But after ten years he's not happy. He feels bad that many clients come back, fat again. That happens again and again, and so he asks if he is really a good gym instructor. Many people don't understand why he does not like paying customers to come back. But I think I understand him.
