Yeah, often times, it wouldn't actually be getting a beer. It'd usually be going out and getting a coffee. For a while, I'd have coffee runs at 2 or 3 PM and take a walk with people.
I think they have a roundabout point in that most people would probably automatically exclude them from this sort of who-are-my-work-friends evaluation, possibly without even realizing it.
Nah I think they clearly hyper focused on the beer drinking aspect. My guess is that they consider not drinking a personality trait.
