Many moons ago I was waiting for the tube at Embankment station in London quite late in the evening, when an old filthy smelly drunk, most likely homeless, came staggering down the steps onto the platform. As he staggered along the platform everyone moved quickly out of his way, as did I. A City gent, immaculate in his pinstripe suit, brolly and briefcase, stood up and took hold of the chap's arm and led him away from the edge of the platform to a seat in the corner, saying, "Come on old chap, come and have a rest on this bench, out of danger." His actions made me feel ashamed of mine.
