During the time I was working in Soho, London, from 2000 – 2005, I used to see this homeless guy around Oxford Street, he would repeat the phrase “yes, twenty pence, please, twenty pence” over and over. He was quite distinctive as this was all I ever heard him say, and at the time I was always on the look out for interesting people around London for a personal project I was working on. One time though I did hear him ask passers by what their favourite colour was.
