What should I do or not do when I am eating in Britain?

The British usually pay particular attention to good table manner. Even little children are expected to eat correctly with knife and fork.
We consume most of our food with cutlery. The foods we don't eat with a knife, fork or spoon include sandwiches, crisps or corn.

Things you should do:
If you cannot eat a certain kind of food or have some particular needs, tell your host several days before the dinner party.
If you are a guest, it is civil to wait until your host starts eating or shows you should do so.
Always chew and swollow all the food in your mouth before taking more or having a drink.
You may eat chicken and pizza with your fingers if you are at a barbecue, finger buffet or very informal setting. Otherwise always make use of a knife and fork.
Always say thank you when you are dished up something. It shows appreciation.

Things you should not do:
Don't lick or put your knife in your mouth.
It is ill-mannered to start eating before everyone has been served.
Never chew with your mouth open. No one wants to see food being chewed .
It is rude to have your elbows on the table while you are eating.
Don't reach over someone's plate for something, ask for the thing to be passedpass.
Never talk with food in your mouth.
Never use your fingers to push food onto your spoon or fork.
It is impolite to slurp your food or eat loudly.
Never blow your nose on a napkin .
Never take food from your neighbours plate.
Never pick food out of your teeth with your fingernails
