Kath came round tonight; first time I've seen her since the 'incident'. Apparently the pub had a long steel trough behind the bar, behind all the pumps. In this trough were small plastic boxes, one to each pump position, that looked very much like margarine tubs. It was one of these, full to overflowing, that was poured into Brian's glass, which she then topped up from the pump. How long had that beer been accumulating in that plastic container?
Brian is a most extremely diffident individual and would have found it difficult to speak out, but he did so, and then the pony-tailed manager snarled at him for saying anything.
