Yes, we did this also. Lunchtime, a few brews, then back to high 
power RF test work.
Even today, a beer at lunch doesn't seem abnormal, but two of them, 
well, depends on the person. For myself one is adequate, two 
excessive (at lunch I mean).

At CERN, the large particle accelerator complex near Geneva, wine and 
beer are sold in the cafeteria at lunch. I don't believe that they 
have lost an excessive # of workers due to it, although they did get 
sabatoged when someone left a beer bottle inside the evacuated 
beamline deep inside the tunnel for one of the large synchrotrons 
there a few years back, and they couldn't get the particles to 
accelerate past the 'obstruction'.

On another note, HF has been erratic this weekend, sometimes 10 is 
really open. Lots of solar activity going on.
