What should we have done in this messy situation?
You should have heedfully explained to him that snacks can be hazardous:
They may contain lactose, gluten, sugar, carbs, and all sorts of chemical weapons that only companies like Nestlé are vile enough to contrive adding into foodstuffs. You can die all sorts of gruesome deaths by having snacks at the gaming table. Point out to the player, if he doesn't stop at once, it is all but guaranteed that he will feel excruciating pains in his abdomen and even lower down.
Be so kind and offer to accompany him to the nearest hospital at once to save the situation.
And to have your boot removed from his butt after kicking it for eating at the gaming table!
Nuff said.
