Most people I know don’t go to bars for an efficient alcoholic experience.
To reinforce what you’re saying, bartenders I know tend to only have stories about one-off degeneracy that happens over the course of one night. But liquor store cashiers have stories about their regulars destroying their own lives over the course of months or years.
I do live in an expensive area, but didn’t mean to imply that the prices I’m describing are the lowest available. Some people choose to go to more expensive places, or order a more expensive option.
