No, but I'd bet there are state laws about unilaterally declining purchases that have been approved by the state. There is no notification given at the register that the person is over their limit (save for the decline) nor is there even any notification that the person is using an EBT card unless there's a problem or they tell you. All the cashier knows is "the transaction was approved... next!"
but the machines did not say the transactions did they? Then how did this problem even get noticed?
