It seems that whenever there is an abuse to the use of food stamps, and the (ab)users whine about it, the new “use” is permitted - so, soon, you can buy anything you want with food stamps. Used to be, if you had change coming from food stamps (long before the card was issued), the individual stores would give you some kind of token indicating the amount. Could only be spent in the store that issued it, though. People whined. Probably the stores complained, too, because it shouldn’t have been their responsibility to provide the “coinage” of the change. So, they were permitted to give “real” change for food stamps. Obviously, this was frequently abused. I have heard of many a person going through the checkout counter with a $1 food stamp “bill”, with one very small item; get the change, go back into the store, buy another very small item in the same way, time after time, until they had enough change to go buy a bottle of booze.
