@hj What's fancy about a cutting board? What stops us from eating from cutting boards at home? Nothing. We just are smarter when home and pick up the plate.

Proper restaurants shouldn't use wooden cutting boards to assemble burgers. It isn't hygienic as the stains on that board prove. Wooden boards suck in liquids. That's why if you cut fish on a wooden board the whole board will smell of fish even after washing it.

Anyway, I'm not shitting on you for eating it, just on the restaurant thinking it is somehow more classy to use a piece of wood rather than a plate.
