Some states now put food stamps on plastic cards, which is much more efficient than paper food stamps. But, a nosy person behind you in line can still see that you are using food stamps. You are free to use food stamps all on steaks or candy if you want. It's nobody's business, and it's not food stamp fraud. But other people are nosy, and that's not your caseworker's fault.
Most grocery stores love food stamps.
Even conservative politicians in bread-basket areas of this country like food stamps because it's pork for their constituents. Any form of welfare is chronically underfunded. No agency has enough workers. I do the best I can. What most clients don't seem to realize is their welfare worker cares more about them than anyone else.
