Anyone likes to chill in the office after work?

I remember before covid at my very first job, I would stop working at 5 as usual, but instead of going home, i would disappear into a conference room and surfed the web until 9pm. I can leave after rush hour traffic and have a whole building to myself. It felt great! I'm surprised not more people do this, though my first company are mostly much older people so they have families to return to
