i've had the same experience with bosses i had back when i had a desk job. it annoyed the hell out of me. they try to strike up a conversation that never really goes anywhere and ends up becoming this awkward moment where neither of us can think of what to say. even times when they force you to do overtime when it's absolutely unnecessary, they just wanted company coz they didn't have anywhere else to go but to work and spend their free time there coz everyone at his own home hates him or something or other.
Chefs who obviously hate their home life, so they never go home, but never really do anything. Just hover, miserably around the kitchen for fifteen hours a day. I got this, go home and play legos with your kids.
