Q: When you are chewing a piece of food, steak, etc. and you are chewing on a bad piece which contains fat, etc. and you want to get rid of it at a restaurant, do you put your napkin to your mouth to get rid of it or do you take it out of your mouth and put it back on your plate?
A: Discreetly place the offending food back onto your fork, and then place it on the edge of your plate, as discreetly as possible. This sounds awkward, so practice at home and you will see that it is both comfortable and hardly noticeable to others at the table.
