I just went on my second date with a guy and I like him but he has pretty bad table manners. On our first date he picked at his teeth with his fingernail at the table without covering his mouth with his napkin or doing anything to try to hide his teeth cleaning and on our second date he touched non finger food with his hands and grabbed food from communal dishes using his personal fork. I don't really want to date someone who I am embarrassed to be seen eating with. Is there a nice way to say your table manners need work? His manners outside of the dinner table are not horrible. He opens doors for me (not his car door) and says please and thank you.
