How Does a Homeless Man Spend the Money That's given to Him?

Okay confession time, I've often thought that when I give money to a homeless person they just spend it on booze and cigarettes. Upon rare occasions I've witnessed said individuals buying food. I guess I'm not alone in my belief, because the person conducting this social experiment believed the same, although the homeless guy just melted our hearts.

I understand that not all homeless are alike and that most on them have no choice for being in their situation. Nonetheless, this homeless guy starts spending his money right away. See what happens.
