You know we're not talking about dogs here, right homie?

Yes, but the point still stands. Everyone loves the grand gesture of walking in and plopping a 20lb bag of chow on the counter or heroically presenting a homeless man on the corner with a brand new The North Face coat with tags on it.

I'm speaking from an American perspective for this next part, so if OP isn't from America they can disregard it, but the whole gift-giving ritual (which this is) makes people feel embarrassed for giving cash outright, like "oh, you couldn't think of anything to get them?" It's a difficult truth to swallow but the truth is that most community closets, food banks, etc. are more than stocked with the goods themselves. Homeless people in most of the country have at least some access to these basic goods. What they don't have is money to save for either A) their specific needs that only they know about or B) some sort of safe housing arrangement.

Same thing I saw when I volunteered at a shelter. Americans love the warm feeling they get when they give someone less successful than them a physical item, but the second you tell them the cash would be more useful they get indignant. It shatters their illusion that they, and they alone, were making some huge expenditure.
