Name withheld, London: 'I met this guy in Covent Garden. He had a friend with him who was doing all the talking and asking for money on the subject's behalf. We ended up in the middle of Covent Garden with his friend shouting at me, saying: 'We need £20!' This guy was a bit embarrassed about the whole thing. They got £50 in the end. If these guys want money, they'll get paid for it. Everything I do is self-funded.'
