If his children need food, fine, give him food stamps for the kids with a mandate they be used for milk, bread, basic veggies, etc.
If he can’t feed his kids what the heck is he doing in “college”???
I’d just eliminate the food stamps entirely and tell him to go to his local church for some food.
You can buy just about anything you want with food stamps. Soda, candy bars, chips..
Food stamp people live higher on the hog that most of us stiffs.
