How to get your husband to use proper table manners
Don't point out the obvious.
Barking orders at your spouse is only going to cultivate passive aggressive behavior. While he may be acting like an animal, telling him could be humiliating.
Instead of whacking his elbows off the table or snapping his jaw closed when he chews, take a more subtle approach. Ask him what kind of table manners were practiced at his house growing up.
