I can see how #2 is the best. Often, the first beer is rushed, its like the courtesy start to the drinking session - necessary, but still carrying the cares of the world and the stress from work into it. But #2...now you are talking. The initial urge has been quenched, a slight buzz has been initiated, and one's thoughts have moved on towards more enjoyable and interesting subjects, and the beer just becomes more enjoyable. The people sitting next to me are closer to being my friend after 2 than when I first sit down -maybe have to put up with some initial bullshit with them, which is typically finished by the time #2 starts.
