Witnessed something odd at the Wetherspoons at Angel today. Ryburn Numpty Bitter was on a handpump. When someone asked for a pint, the pump was not pulled, but instead the tap, common with Wetherspoon pumps, was turned to fill the glass. Turned out that the beer was under pressure! Is it possible to connect a gas line to a real ale cask, despite being a highly dubious practice.
