In my town at least.
Maybe decades ago the argument could be made that they're social hubs for people to unwind, meet and have a good time on a weekend.
Nowadays they're just hovels where mostly retired old boys go to binge drink in the daytime and cost the NHS billions in the various cancers strokes and host of other comorbidities that crop up.
The three biggest ones in my town are the typical chain owned leasehold places. Big companies that own hundreds of pubs all over the country. They treat the leaseholders like crap, if they start to turn a decent profit they up the rent.
