when i got a job based at a town hall in the 1980s, there was a staff bar in the basement.
it was meant for after hours, late working, meetings etc.
not sure how it was used, i haven't drunk alcohol since i was 16.
anyway, within a few years it disappeared, on the grounds that the space was needed by reprographics.
then it was a known rule that you were not meant to drink any alcohol during the working day, even during lunch hour if returning to work afterwards.
again, i am not sure how well this was observed.
my job was mostly outside the office and our dept was generally more aware and observant or rules.
