Slops

The stale leftover beer in the pint glasses of the local pub, collected up and put back into the barrel to resell the next day. Many moon ago in yesteryear, when local publicans at your nearest watering hole were less honest than a Politician on polling day, pubs in the UK used to only serve up foul mess labelled lager - not your craft wonders and fruity ales of today's youthful world. To put money back in the till at the end of a torrid evening of sales, the landlord of public houses would collect up the 'slops' left at the bottom of everyone's beer glasses and return this stale beer back to the barrel. As most people would be only drinking a choice of 2 lagers, it didn't really matter what barrel they went back into, nor that they made the beer taste rancid. As they never cleaned the beer lines, you couldn't tell if it was that making the beer rank, or the slops from old Coughy Jack's leftovers being the cause for the slightly chewy beverages.
