When I first came to the church that I pastor, some 34 years ago, I soon discovered that the former pastor had been a "soft touch" and handed out cash indiscriminately to anyone who had a tale of woe. I often wondered if there were some hobo code chalk marks outside that read "suckers live here".
It is almost impossible to weed out the truly needy from the grifters, so I came up with a plan. I had been buying my gasoline at a store down the street, and made an arrangement with the manager. I put $50 in their care, and told them that if someone came in to the store with my business card and a request written on the back with my signature that they would honor it. "$5 gasoline", "A loaf of bread and gallon of milk", "Pack of diapers", etc.
Over the next six months, I handed out dozens of these cards. Not one of them was ever redeemed. They didn't want anything other than cash, and didn't care what lies they would have to tell to get it. I eventually pumped that $50 into my gas tank and shut down that failed experiment.
One more story with an important point: We had a special speaker on a cold winter Sunday night. He ran the city's largest homeless ministry. Before the service started, a woman came in and asked if we could help her with $18 worth of propane. She, husband, and infant child were in a motor home on the way to new work in Oklahoma. They had gas but no propane.
I told her that I didn't know where to buy propane on a Sunday night, but that our guest might. He came out to the foyer, and told her that he didn't know either, but he could call his friend who ran a family shelter where they could stay the night, and have a good breakfast before heading out the next morning. The lady said "My husband is too proud to stay in a shelter", to which my friend replied "But he isn't too proud to send you into a church to beg. What you need is a warm safe place for you and your baby to spend the night, and I have told you that we can provide that." She turned on her heels, and walked out in a huff.
The point is that often people think that they need one thing when they actually need something else.
