Op programs like EastEnders, and Corniation St give the impression that everyone is constantly in the pub.
Long time since I've really watched them but they use the pub as somewhere to develop the story lines. Same as the cafe and the laundrette. None of the characters seem to commute to work either. I don't know anywhere where people live and work 10 secs apart.
I'm going to draw an odd parallel, churches and pubs.
Both were community hubs, which are struggling with falling congregations. Pubs and churches are closing every week.
People went for the social experience, to meet people, keep in touch with others. They were places where local news, information was shared and passed on.
Lots of social events were organised in pubs, football teams, darts, pool leagues. Dominios, and cards. I even knew one with a library shelf.
Churches had guilds, carpet bowls, various committees, toddler groups.
I'd think it's a combination of better entertainment options at home. Tv used to go off during the day so the pub was as much about company as it was about the drink.
Thinking of lots of stuff the local Facebook is used for anyone know a plumber, kids football club, where to get a dogwalker, all that info would have been shared in the church and the pub.
