1. When asked what you want to eat, remember not to say "whatever". "Casual" seems easy-going, but this is the last thing the younger generation can say to their elders and subordinates to their superiors. Your casual is equivalent to the oral part that your elders asked you. They will be very upset but will not say it.

2. Try to let others choose the main course. When the elders ask you to order, you don't know what the whole table likes, so on some main courses and expensive dishes, let the main person at the table decide in a selective tone, "Do you want to eat bass or mandarin fish? Shall we order heavy seafood or light seafood? " And so on. Regular side dishes and snacks should be able to recite seven or eight things without looking at the menu. The standard of this meal had better be made clear in advance. If it exceeds the standard, it will be wasted. If you can't meet the standard, it will appear that you don't value the guests.

Touch the cup with both hands, the cup is lower than the other side. People who take an intermission can stand up, but they must sit down before drinking.

4. Sit in a position convenient for greeting drinks and meals, that is, the position usually left by others after taking a seat, and it is also convenient for communicating with the waiter.

5. Speak less and listen more, eat less and watch more.

6. Don't play with your mobile phone, answer the phone and go out.

7. Don't shake your legs and sit down.

8. Eat less things with bones, such as ribs, or you will eat a lot when you pile them up at your desk.

9. You need to monitor the amount of alcohol in the wine dispenser, the amount of water in the glass, and the drop of chopsticks.

10. Remember not to pose as "I know this problem" and be modest.
