What snap does is pay for the recipients’ tattoos, dog food, beer, weed, and scratch off lotto tickets. If they don’t have to pay for their food they can spend their money on important things
My first hourly job was at a supermarket in the early 1980's. I saw all the grift even back then.
At the time, SNAP was "food coupons," the actually paper "food stamps" that we still call it. Any odd-cent purchase was given coinage change. $19.05, and they got $.95 back in real money.
One of the games the grifters played was buying something real cheap, multiple times in different transactions, and using the accumulated change to buy cigarettes. It infuriated us at the store, but couldn't really do anything about it.
Oh, and we usually carried their ill-gotten groceries to their late-model Cadillacs in the parking lot.
