This Reddit thread shares the map of all the pubs in the UK. The Poke picked it up and wrapped it into some more links and quotes. Apparently, not even all the pubs are covered:
“Nope. There’s at least 12 pubs missing from the north coast of Scotland. Thurso alone has more than 6, 2 in Bettyhill, Tongue and Melvich plus a few others all missing”, writes shaidy64
The source of the map is here referencing 24,727 UK pubs. And I’ve only been to like, what, 3? This situation urgently needs correction.
