To Beer or not to Beer.

I recently had lunch with a friend and we went to a local lunch hot spot.  When I was asked what I wanted to drink I decided on my usual Cranberry Juice & my friend opted for a Mixed Drink.  I was a little perplexed cause it was a work day and we both had to go back to our respective office.  Is it really okay to have a drink during a work day?  Each company has policies about drinking on the job and some disciplinary action if caught drinking on the job.  My view ~ if you have the urge to drink ~ drink water.
