CLEANLINESS

You can't disagree with this. 

We have tables to the we keep our food off the floor.
We have table cloths to keep our food of the table.
We have place mats to keep our food off the table cloth.
We have plates to keep our food of the place mats.
We eat pizza or carry-out in the family room to keep our plates clean.

More food stuff.

Knives and spoons go back to the cave men.  Forks are only dated to the Middle Ages - maybe a thousand years ago.  Chopsticks go back 5,000 years.  Between China and Japan, 70 billion chopsticks are sold each year - that is a whole bunch of trees.

In Inda, Africa and the Middle East, most people eat with their fingers.  They use their right hand only - the left is reserved for other tasks.  I think they slurp their soup out of the bowl.
