<human>: Could you distill the essence of the text into 1-3 sentences?

At my previous job I had a supervisor who loved me, he fawned over my job performance, wanted to hang out outside of work (which I never did), and just generally went out of his way to get my opinion on things and cater to me.  He didn't know, but I HATED him.  I know, it seems somewhat backhanded to dislike someone who goes out of his way to cater to you, but I didn't dislike him for how he treated me, I disliked him for how he treated everyone else

He had a group of employees that he completely catered to, he wanted to advance our careers, he wanted to be our friends, etc.  To everyone else he was a nightmare, he'd intentionally assign these other people awful shifts, he'd make them work on holidays, he'd dismiss their complaints and concerns out of hand, he'd treat them like second class citizens basically.  And he'd intentionally sabotage their relationships with management, which I had witnessed him do, and heard him brag about on numerous occasions.  It was strange, the people he liked and disliked seemed kind of arbitrary, but I did notice that the people he liked were disproportionately male, and often geeky and/or gamers, but he did pick up a few others along the way that had no connection to those characteristics.  

Anyway, because of the way he back stabbed and undermined people he didn't like, I intensely disliked him.  And you might ask why, if he liked me, didn't I stick my neck out for the people he treated badly?  I did, but he laughed it off and said they didn't have it as bad as I thought they did.  

Fast forward a year, and now I'm at a new, and better paying job and I get a phone call from him, wanting me to hook him up with an interview.  And I was briefly very confused, I thought to myself, "But I HATE you, why would you think I'd go out of my way for you?"  Then it occured to me, he never knew.
