Hmmm how about a description so I can decide if I want to take a chance on clicking?
this guy gives some money to homless guy, then homeless guy goes buys some stuff for himself, the first guy comes back acting like he is in need of money to buy medicine for his daughter so the homeless guy goes back gives back the stuff he bought for himself and gives the money to first guy... who gave him the money on the first place...
(btw homeless guy does not know that in the first place the first guy gave him the money ...)
