I cant vouch for a $41 ice cream cake story but I have absolutely seen the system being taken gross advantage of. One of my first jobs was stocking shelves/bagging groceries (this was still a thing at some stores back then) at a local super market. Anyways, this was also back in the day food stamps were actual paper vouchers and the users got their change back in cash. Used to see all kinds of people come in and use their food stamps to buy a packet of Kool Aid (for however many cents they were back then) and then take the change over to the Service Counter and buy cigarettes, blunts, chew, etc. I believe the system is much better now that its electronic with the cards but I am sure there is still a way to exploit it and people doing it.
