Same as cigarette smoking in the movies. SALES AND PROMOTION
Some if not all movies were subsidized by Liquor/Beer/Tobacco companies for encouraging Liquor/Beer/Tabacco. Acceptable patterns of behavior. I smoke, drink occasionally, although I have a built in 'governor'. I call for 'RALPH' at the kamode very easily and a couple of drinks for me in the day is like a sleeping pill to me.
I had a Bar/Lounge/DriveUp Pkg store for 12 years. If I had a couple of beers with customers during the day, say Goodnite.... I had to go take a nap.
Good thing, I never found a favorite drink, drinking up the profits is not good business. PLUS if inebreated ? OK Drunk on my a$$, doesn't help monitor the business, customers, help or could get you killed.
For a small Lounge Pkg store, with live Band Entertainment on Fr/Sa/Su, I did pretty well. Gave my employees health insurance, better than average wages and THEY STILL STOLE FROM ME. Putting in cameras sure helped, but pi$$ed a few people off. You wouldn't believe the methods used to cheat the employer.
