Having a drink with the colleagues has nothing to do with alcoholism. I used to organize nights out with colleagues even if I was never drinking alcohol (I had to drive). But the point in "going for a beer" is socializing and informal communication, not the beer.

The internet has done a great job illustrating the huge range of what people think “normal” drinking looks like.

There are a surprising amount of people that think anybody that has ever been drunk is an alcoholic.

Obviously having a drink with the colleagues has nothing to do with alcoholism.

I was responding to the comment that 'in the extreme, alcohol is a truth serum'. It isn't.

I don't think they meant extreme as in repetitive use.

I think they meant when you've drank enough to be drunk.

e.g it's not very effective as a truth serum if you've only had a little.
