I just eat normally, don’t worry about it too much. You can subconsciously open your mouth overly wide, so the food does not touch your lips on the way in…..but who wants to sit in a restaurant looking like a goldfish????
Some ladies just touch the corners of their mouth with the serviette/ napkin. Usually, you will find that a lot of girls go to the ladies room between courses to ” freshen” up .
If I am at home, I don’t usually wear lipstick at mealtimes……the number one rule is probably….
Open your mouth before you put the food in…. otherwise it CAN get messy….😋
