You'd be surprised.  Of course none of us know the laws as they apply everywhere but on my recent trip to California I was in a Savemart and swiped my card.  I could choose from Credit, Debit, or EBT.  For some reason I hit EBT, I guess I was thinking Electronic Banking Transfer or something.  It asked for my pin, if I wanted cash back, etc.  I selected cash back, probably $20.  I waited for a second and the clerk told me I hit the one for food stamps.  I was in uniform so I made a joke about how the news always says the military gets food stamps.  Then I said, "you can get cash back on food stamps?"  To which she replied, "yeah, isn't that something?"  Mind you my beer and/or liquor rang up no problem.
