Would you clarify this about removing food from ones mouth - you indicated that if a piece of food is disagreeable, you should "move the food forward with your tongue onto your fork and place it back on the side of your plate." What if an individual is in the process of eating a steak and comes across a piece of gristle? To remove the gristle from ones mouth, I was taught that you should quietly deposit the contents into your napkin, and place the napkin to the side of your plate.
Dear Please Advise,
Gristle is also deposited back onto the fork and placed at the edge of the plate. Done discretely, no one will notice the gristle removal nor the location of its deposit. Any food removed from the mouth is taken out the same way it was put in.
