― Jules Renard, The Journal of Jules Renard
Eat only what you can handle. Never eat too much, not only will you feel ill, you will look impolite and greedy. However, don’t eat too little, and whatever you do, don’t abandon a dish. It could seem incredibly impolite if you are served food which you then don’t touch. If you are served something you dislike, try to eat it anyway, to be polite. If you are served something you are allergic to, politely tell the hostess this, preferably before she puts it on your plate.
