I have seen many homeless people in the midwestern metro area where I live and have given a few of them that I have met at the exit ramps to expressways money. However, I am also hesitant to give them anything for the reasons that have been stated by others and because of a couple of experiences that I have previously had with homeless persons and a story that someone told me of their own experience with a panhandler.
I once came out of a bank and was approached by a homeless person who asked me to give him some money so that he could get something to eat. Instead, I offered to take him to a sandwich shop a short distance from the bank and buy him something to eat and he refused that offer and said he wanted money instead. I also used to work at a church which had a kitchen with a walk-in refrigerator and freezer and was approached one day by a homeless man who used to hang around the church and frequently ask the ministers and staff for food and money. I offered to make him a peanut butter and jelly sandwich which he refused saying that he did not like peanut butter and jelly and then asked me if I would instead give him some money so he could go to Subway to get a sub. What I wanted to tell him is that beggars can't be choosers but did not tell him that and did not give him any money because I felt that if he was really hungry he would have accepted and eaten the peanut butter and jelly sandwich. Finally, I was also told a story by a woman who followed a panhandler home to a house in a very affluent neighborhood and then knocked on the door to confront the panhandler about that and the panhandler refused to answer the door.
The bottom line for me is that while some people may genuinely be hungry and in need, you cannot know for sure which ones are and that unlike some of the people who have expressed opinions on this topic, I do not believe that giving people money is a good idea because their use of it to buy beer or other alcoholic beverages, cigarettes or illegal drugs hurts and does not help them and merely feeds a destructive and unhealthy addiction and habit. Therefore, I will only give homeless people food.
