Yeah, I know kids from the late 70s/80s who would spend a day going from convenience store to convenience store buying $.15 or $.25 candy or unsweetened packs of Koolaid with $1 food stamps because they would get $.75 or $.85 in real money change. By the end of the day they would have $20 or $30 or $40 in coins, which could then be used by their parents to buy cigarettes, beer, gas, or whatever else the food stamps couldn't be used for. When they ran out of food stamps they would go to various churches (in a larger city) and get free bags of random food and sometimes fuel vouchers, probably so you would drive far enough away from their location. Tip - if you make corn flakes with powdered milk, it gets soggy in less than a minute, so eat it fast. Some of these kids went into the military, or eventually college, or are self-taught managers, and most have successful careers and own their homes. There was one who went into construction and hasn't been doing so well lately ...
