When a dish is served,do not content yourself first.Ask others/ senors to try first.Or help to fill his/her plate with the food.Don't chew like a horse,don't burp.Never think about break the wind!
Have small talks with eating.Propose a toast three times.Then start with the most senir drinking to his health or whaterever.You bottom up to show sinserity.One by one till you finish with the last person.If you feel like vomitting.Excuse your self to the bathroom.If applicible,use a finger or two to poke your throat to induce release.Back to the table,as if nothing happened.Drink for another round.
