I'm trying to understand why you carve an exception for this one individual.
When I worked in restaurants, the owner and I had a very interesting conversation after hours, and with beers, about his thoughts and feelings being responsible for the well being and livelihood of everyone that worked there. It was a positive moment, I thought I had a great boss, I work my ass off for him.
A year later I found he was trimming hours off of my paycheck. I quit on the spot. Months later I heard he did the same to the waitstaff tips and it wasn't much longer before it all fell apart.
People can appear very different publicly than privately, and they can change over time.
I'm not saying anything groundbreaking here. Humanity is complex and varied.
