Preston Brewery Tap won't even notice the difference in clientele.
Prices in the Crown & Anchor will certainly scare 'em off.
And there's no way way they'll get served in the Park View. Same as everybody else really. Nobody gets any kind of service in that ShitForService pub.
They've confined themselves to one small section of the park. Maybe, say, a fifth or a sixth of the total area. Not causing anybody any harm whatsoever. They'll move on soon enough.
Live and let live maybe?
