There's an ex coworker that comes to mind. He was the typical wishy washy dude talking a lot and doing nothing all day and then crying to management of how much he was working. I was managing a nightmare team and teaching tech workshops inside the company. We never worked together. I never liked the dude much but I was trying to get his jokes though his thick British accent and trying to be polite. Turns out he hated me for some reason and actively stopped a referral I tried to bring into the company. Years later I even offered him a referral out of courtesy which he didn't pick up on. Even more years later I found out he vetoed me from some company I applied years ago with no specific reason.
