What I said during the next commercial is, That this is not a stupid question soley because buskers are often treated as beggars. I won't give beggars a nickle. A good busker, even if I don't have time to listen long, gets cold hard cash, because I appreciate both the effort in the performence, and the effort prior to the performance in attaining that level of skill. I need all the good karma I can accumulate, so I kick in for buskers.
