"We bleed friendship and work together, so it’s hard to tell when we’re discussing work and when we’re chatting over beers"

Isn't that potentially a bad idea from a work/life balance point of view? I like to know at the end of the week that I'm free to do my own thing - feeling compelled to go out drinking with co-workers and talking about work-related subjects would stop me relaxing, and would be bad for my productivity in the long run.
