I think this is a great balance and something I'm interested in trying more. I have three displays at home and four displays at my co-working space desk, but I'm interested in periodically using a local pub for sessions of 2-3 hours to do single-screen work over a beer. e.g., dealing with emails, invoicing, etc.
But seriously, how would it be a problem? In the afternoons, we often have a beer at our desks while working. I often work at night after having a drink at dinner or in the afternoon after lunch at the pub. Having a pint beside the laptop while answering emails or working on a side project or making content changes for a client wouldn't be especially difficult or problematic.
I've worked for myself for 20 years (http://www.isaacforman.com.au/) so there are rarely issues with time and place of work either. I'm mostly anchored to my desk because I like the room to move of four displays.
It never occurred to me to be desirable to mix alcohol and working. I don't drink much but if i choose to have a pint it is as a reward after finishing work. It's like a ritual that delineates clearly that work has finished and it's time to unwind. That feeling is practically the best thing about the pint.
