Everyone "knows someone" that offered to give a homeless person food in lieu of money and got turned down because they wanted the money instead. It's such a ubiquitous anecdote that part of me always wondered whether it was one of those urban legend "I knew a guy" tales designed to make people feel better about not giving money to the homeless.
After all, it's not hard to see how something like that can spread -- Carla "knew a guy" that related this story to her, and while talking to Jason, in the interest of getting to the point without too much explanation, she says that she "knew a guy" that did this. Jason does the same, and so the story spreads without ever being more than one degree of separation from its supposed origin.

So I pull up in front of the Caribbean restaurant I decided to visit for lunch, and as soon as I got out of the Jeep a small, unkempt middle-aged woman carrying a couple of plastic shopping bags comes up to me and asks me for a dollar. Knowing I didn't have any cash on me (I was paying with a card), I told her I didn't have anything and turned to walk away. But I was feeling generous. The restaurant I was going to sold full meals including salad, rice and beans, a protein of choice, and plantains for under $8. Easily over 2 pounds of great food.
I turned back to the woman and told her, "Look, why don't you pick a meal off the menu and I'll get it for you."
Her response came after a brief moment of pause, obviously she hadn't expected the offer. Then she said that what she really wanted was some yellow rice and fried something-or-other, items that they didn't have at the Caribbean restaurant but that she could get elsewhere if only she had the money.
Disappointed (both in the offer's refusal and in the stereotype having been proven correct), I smiled at her and shrugged before walking into the restaurant, my good deed for the day remaining unrealized.
Of course, I know this was just one example and that not everyone would be so quick to dismiss a free meal. Still, it made me uncomfortable, this little homeless woman trying to take advantage of the giving nature of people.
And I don't like the fact that I'll probably think twice next time, before offering help again.
I liked it better when I could think it was just a folk tale.
