If he would be smarter and know how to increase his chance of success, he would position him self in better position where he would be closer to people and thus breaking the zone barrier people have to cross, and not standing in the dead spot. Better spot would be exactly opposite where he is standing, where the people are coming from, and not where the people are not going. He could also go to wilderness and play there and after complain that nobody had given him any money. So yeah i learned that people do not think before they act, but instead are doing and never correct their fail. He should study sociology and body language after play on musical instrument.

Maybe he was ashamed that he have to do his money this way and that is the reason he distanced him self from people, and most of the people can feel when somebody is distancing him self and react intuitive and do not approach because they feel something is not alright with that person.
