Pub managers/landlords with 'thuggish' attitudes/personalities
maybe define the culture of their establishments
and tend to attract a similar type of regular customers....???

Add rumours of drug dealing to the equation,
plus frequent assaults,
then at least our local police force take a very stern interest
in long term monitoring of the premises.

Over the years, our local paper has fairly often run headlines on police busting nuisance pubs.

One really shit town centre Karaoke pub has been shut down permanently,
which is no loss to anyone apart from a gang of squalid bonehead arseholes...
The town is much better off without it's over loud threatening presence...

Unfortunately really excellent relatively well run live band venues have also been forced out of business
due possibly to trumped up complaints from 'concerned citizens'
[ NIMBYs and/or cut throat rival venues...??????]....
