It's Peanut Butter Jelly Time!

I don't think I quite understand why every time some organization has a food drive, they always ask for peanut butter, jelly, and usually canned tuna. If I were on the receiving end of said food drive, I'd like a $20 gift card to the supermarket to blow on organic bread or soy milk. Not everyone likes peanut butter and jelly. Not everyone likes tuna. And just because I may be hungry/homeless/whatever, doesn't mean I don't want chicken, beef, or mashed potatoes. Used clothes drive? Yea, that's fine, I like vintage or previously worn items. I'm ok with that. But at least spring for a little more than peanut butter and jelly. Besides, I'm allergic. Pass the salmon please.
