EBT payment was not working so...

My wife and I were recently at the grocery store and there were two young mothers in line in front of us.  They were trying to use their EBT cards to pay for the groceries and it wasn't "going thru".  The groceries were completely bagged up and ready to go, but without payment the cashier was preparing to call for assistance to restock all of the items and send them home empty-handed.  My wife glanced over at me knowing that this would be a situation that we could assist with.  I nodded in agreement and we told the cashier that we would be happy to pay their bill.  The young ladies were very confused at first, but once they  figured out what had happened, they immediately began crying and gave us both very emotional hugs.  The total bill for both was over $180 (they had a lot and groceries are expensive you know) but it was well worth it for the joy that we shared with them that night.  It wasn't a "stealthy" act of service since they knew who we were, but I thought I would share it.
