Top 5 in Top 10 leading rules in Western high-end cuisine.
You are not started to eat until everyone has been served. If there is a large amount of visitors, the staff can tell you how you can start before everyone is served.
If you are eating something that has ice or pips in it, you can use the index finger and thumb to grab them out of the mouth. Put them on the side of your plate. You should never use a toothpick at the table, you shouldn't have a nose. If you have something stuck in the tooth that you have to remove, apologize and go to the bathroom to remove it. It is also acceptable to remove bones with your fingers.
Don't take more salt your meal before you've tasted it; It is an insult to your host if you need salt, use a clean knife head (if the salt spoon is not supplied in the salt plate) to turn a little salt to a side of your plate that you can use to embed.
Pre-dinner snacks must always touch your plate before putting in the mouth. Don't take it from the serving tray and put it straight into your mouth.
