Not all homeless people are alike and anecdotes are not data but while we're talking anecdotes I once gave food to a homeless couple and they sheepishly asked if I minded if they gave their dog some of the food I gave them.

Of course I was happy to see their dog get a meal as well.   

I'm not really sure what your point was unless you're trying to paint all homeless people as greedy bastards who don't need any assistance at all.
