I've seen homeless people with working cell phones before... LOL.
Yeah there are some unscrupulous people out there. But there's also two kinds of homeless people, those that want to help themselves and those that are very content to keep living the lives theyre living. One time when I was about 22 or 23 I saw a guy outside a convenience store begging for change. He said he was hungry. So I asked him just straight up if he wanted me to go inside and buy him a sandwich or buy him a beer. He chose the beer, so that's what I bought him, made his day and it made me feel good for some reason too.
