Explain in detail the principle of the casual table setting. Answer should be not more than one or two paragraph.

The casual table setting follows a simple and informal layout, typically used for everyday meals or casual gatherings. The main principle is to make guests feel comfortable and relaxed, with a minimal and uncluttered table arrangement. In a casual setting, the table should be set starting with a placemat or tablecloth, followed by a dinner plate at the center. A napkin can be placed to the left of the plate or on top of it. Silverware should be arranged in the order it will be used, with the fork on the left and the knife and spoon on the right. The glassware should be placed above the knife and spoon. Overall, the casual table setting is meant to be practical and welcoming for the guests.
