Should ‘Buffets’ be taught in school?

Just went to Chinese buffet… saw too much stupid American behavior. Little kid touching the food and pushing utensils into the trays…without adult. Teen girl touches top of a plate… then puts it back on top the stack.

Looks like people need to be taught manners and require certification before going to buffet
