You just have to live in the right city with sufficiently high rates of alcoholism! In Fargo, ND you could get a tall 200 lb+ man proper sloshed over an evening downtown across 5-8 bars for $50 or less as recently as 2019. Not as cheap as drinking at home, but enough that most folks without kids working full-time could do it every other weekend.
$50 fro 6pm-2am is cheaper per hour than a movie ticket or dinner at a restaurant, and hitting that many bars is easy when they’re all on the same 2-3 block stretch!
