7. Right place for your bag
This is the most common mistake we all do. We need to keep our bag in the right place rather than placing it anywhere you find an empty space. The right place is on the back of your chair or a special stand provided for the same purpose.
8. Do not Refuse
When you are offered something, never refuse it rather take something and leave it on your plate if you do not want it. Refusing may offend the offerer.
