Is that what they did, or was it the last straw? Because if his post-employment behavior is any indication, this guy might have been a total PITA screw-up. Did he steal food for himself, too? Was he unsanitary? We don't know anything about the situation apart from his own self-serving pity party.
He got fired. The manly thing to do is to move on, not make a public spectacle of himself. Big crybaby.
You are now sliming this guy with no evidence. All that’s been reported is he gave out five muffins and some tartar sauce packets. And he was written up about it. No evidence that he was unsanitary or stealing food for himself. Sheesh, get a little distance.
