Begging or busking, if either offends you then you need to find a life. Beggers are generally people with drink/drug/mental health problems who really need to find help that money cannot buy.
          Musicians, jugglers, poets, painters etc are artistes and it is only the philistines and artless folk of this world who find any of them offensive. If you don't like it, don't pay. Simple as that. Although I suspect you'll happily go and pay 10 quid or more for some dreary crap like a Coldplay CD because some stupid mag told you they are the best band on the planet.
          It's all about mind conditioning and it is enforced upon the individual from an early age.Your parents, school, T.V, The Beano, The Sun. If you are a free-thinking, nonconformist who can take a step outside of 'what you were always told was right' you will realise that anyone making a living outside taxmans vast and unforgiving web, or surviving beyond the matrix of this so called society without hurting anyone should be applauded. They deserve MORE than they get for setting a wonderful example. Just because you have wasted a third of your life in the wrong job paying taxes to a government you don't like or trust don't expect everybody else to.
                LIFE IS TOO SHORT.......ENJOY IT!
