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 must say no. Then the host insists again, and you must say no again. The host insist a third time, and you 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, never empty your cup or glass. When it is less than half full, your host or neighbor will refill it. Never fill your own glass. This means that the host always keep an eye on the guest's glass all through the meal.
