But that's not true! You give them plenty. Angry glares, I bet. Heaps and heaps of ill will. You give them scorn. You give the the benefit of your wise sanctimony and offer them the shining example of someone with the ability to consider a fellow human being as nothing more than a speck. You sir, are a fountainhead of wealth for panhandlers. And you even give them something genuinely good, believe it or not. You give them the knowledge that no matter how low they sink, no matter how deep in pits of poverty, mental illness, drug addiction and despair they ever get, no matter that they might lose a limb to frostbite or gangrene, they will at least never be so much of a contemptible asshole as to judge every single individual in a group based on the sensational and anecdotal tales of a scammer or two. They also get to know that even if they spend all their time muttering the word "walnuts!" to the griffins in their beards or shouting at street lights, they'll never be so delusional as to take up such a posture as yours, or believe that such a pose in any way mitigates the fact that they refuse to give solely because they are a selfish and cheap cunt.
Others might give them money, but it takes a real special individual to make a homeless guy think "there but for the grace of God".
