In my sleepy little town in the 60’s, only the alcoholics went out to a public bar. Most people had a small hidden cabinet like area where they hid their bottles of booze. There was minimal drinking even at parties & those who did drink slipped a bottle out of their hidden cabinet for a quick snort away from their friends & family. To make sure nobody noticed, they filled the bottle back up with water so the bottle never appeared to go down.
My first time in a bar was after i moved to Washington DC in 69 where they kept free peanuts, pretzels, & chips on the bar for patrons to munch on so they’d stay thirsty & drink more. IF you were starving you could order a hamburger with fries or a simple deli meat sandwiches with fries & some of the nicer places might offer a steak with baked potato (no salad). The food generally was horrible & few ordered a meal at a bar. They left the bar to go to a nice restaurant to get as decent meal.
i have NO idea what was offered before 69 as I had NO experience until after i moved away from home!!!
