I remember at the beginning of the pandemic and everything was shutting down, the Denver Mayor declared liquor stores non-essential. Within a couple of hours every liquor store in the city had a line around the block. Every news station in town was covering it like they couldn't believe what was happening.
The decision was reversed a few hours later.
All those liquor stores aren't stying open because of a few "heavy drinkers". See how many stores are within 5 miles of your house.
The Frankfurt Airport has at least a mile or a mile and a half of people movers. JFK isn't much better, really big airports.
