I have to say that I haven't met an aggressive beggar in London. In New York, crossing 58th Street from the Plaza Oyster Bar to the Wyndham Hotel, I came up against a huge black man in a long, dark overcoat who said, in deep and threatening tones, "Give me fifty dollars!" I managed to ask him if he would be content with thirty-five and, rather to my surprise, he said, "All right, give me thirty-five dollars!"
