What do you do for dinner or table manners? And how should seats be taken?
When someone delivers a business card, do it with both hands. When delivering knives and cutlery for others, knife and fork: sharp, head delivered to yourself. You may say "eat" politely, but don't make food for others (except your wife and mother). Do not force others to drink (alcohol) - feel free to pull chairs for women and ask her to take a seat. The host and guest should sit next to the host (that is, the paying and paying persons); sit on the inside of the seat (at the entrance; the seat faces the doorway)
A table of people eat, only eat their own share, don't put that out of others - don't eat overeating, delivery: send your name card name card to someone, your hands, and let others can see at a glance on the name card content (not down or other direction).
