As much as I like the idea I'm not sure how that would work with regulation and selling only to 18-21+ (depending on location, some countries might be even more strict?) I'm sure there's online booze selling but that probably requires KYC or some form of identification? Although come to think of it I can order alcohol from with the grocery delivery without much trouble so maybe I'm overthinking it.
Not a huge drinker personally, but it's definitely a cool once a year thing!
