For reference, Oklahoma has quite a history with alcohol prohibition. The state retained full prohibition until 1959, some 20 years after the 21st amendment and repeal of the Volstead Act.
Liquor by the drink, aka bars, were not legalized until 1984. Before then you had to pay a membership fee to join a "private club" where you could then have a bartender pour you shots out of "your" personal bottle that was kept behind the bar.
Oklahoma had 3.2 beer until 2018 when it was repealed by state referendum.
