I saw a couple of things I wanted to comment on in your post.

First of all the EBT ( Electronic Benefit cards) not only have food stamps put on them ( if the user is approved for them ), They also have a cash section, for those on cash assistance and some childsupport payments as well

The cash and child support part of the card can be used in any ATM machine for the most part, casino or otherwise.

Now the ones on cash aid, perhaps shouldn't be taking money out at a casino, but the ones that use it to recieve their child support payments, well IMHO that's their money to use as they need or want.

As far as the restaurant thing goes, They should have stuck to the old rules of not being able to buy prepared food or at least made some state issued ID that says they are eligable to use that service.
