As an introvert, I appreciated the beer fridge when I first started because it helped me get to know the other introverts (everyone). At the time none of my IRL friends were in this sort of work environment so it was something to "brag" about. Back home my family had these visions that my workplace was like google or something and I'm sure they also bragged.
Four years later, I haven't had a beer at work in a long time. At the literal end of the day, I want to go home, relax on the couch and hang with the wife. Right now I'm looking around for a new job because I've realized the current place's motivation for the beer machine is to use as a distraction for the uncompetative salaries and lack of benefits. I geniunely like my co-workers, but the company not so much.
As a side note, all my friends do military contracting type stuff work and get paid substantially more. Four years later, perhaps the jokes on me.
