Drinking, it's serious stuff
In 1928, drinking was a focussed task. Beer parlours were only for drinking — eating, standing, singing, dancing, gambling, and music absolutely weren’t allowed. From 1928 to 1957, the sexes even had to be separated in drinking establishments. If cocktail lounges, beverage rooms and restaurants wanted to serve men and women, they were required to have a separate beer parlour for each sex with separate entrances and no communication between the rooms. Women weren’t allowed to sell or handle beer in a parlour.
