Depends very much on who and what kind of job. When I delivered pizzas, a pint with the other drivers was a nice unwind - complain about work, talk sports, eat some snacks.

Fair enough, I can see that. I would probably duck work and most school social events but did hang out with people from some classes otherwise due to having grown up in a fairly small town that is just outside two large metropolitan areas, I've been pretty lucky to never feel like I was lacking friends as no one really "moves away" and everyone I knew growing up tends to always be within 2 hours (usually closed to 1 hour-30 minutes) travel if we really want to hang out so I find myself very lazy with voluntary socializing. I'm also not into more mainstream hobbies so I'm typically just being a polite conversationalist with most people when socializing with new people unless I can pinpoint something of mutual interest.
