The Still, Lincoln

We visited Lincoln on the last day of our tour and decided to have a drink at The Still.The pub had three cask beers Pedigree Mansfield and Hobgoblin,i had had a pint of Mansfield the day before in Boston and enjoyed it, but the pint i was served was flat and cloudy and quite warm.I returned it to the bar and after a short wait the manager said someone must have knocked the cask.The manager changed it for Pedigree which was ok he then served two men with mansfield from the pump which had been used to serve me the cloudy pint. No more visits to the Still for us.
