Which again is a lazy. It's silly.
I answered your question. I don't think they should be able to get cash from them, then I gave you the reason I think that. You should make an attempt to engage your brain while you read in some way other than OCD grammar nazi "witticisms".
I don't think they should be able to get cash from these cards at all, let alone using the excuse that cards that are supposed to limit HOW you can spend the money need to be accessible in areas where none of the items you are limited to can be found.
For instance in magical PoorPeoplistan where the MJ shops and strip clubs are plentiful but there are no grocery stores. In such a pakce why should a card limited to specifically grocery items be accessible at all?
