People always offer you more food.

People always offer you more food. The host will ask you two or three times if you want more food. First, you could say no. Then the host insists again, and you could say no again. The host insists a third time, and you could finally say yes and take a little. If you really don't want any more, take very little and leave it on your plate. It is the same with whatever you are drinking. During the meal, when your cup or glass is less than half full, your host or neighbor will refill it. It is polite to refill your neighbor's glass. This means that you should keep an eye on your neighbor's glass all through the meal.
