holding their knife and fork in the wrong hand. They were struggling to eat properly and looked ridiculous. eh? I eat with my knife in the supposed 'wrong' hand, if I couldn't eat with it there i wouldn't put it in that hand!
why is anything? Why do we use cutlery at all if you go there? Some people don't, and even eat from a shared communal dish. well exactly, some people use cutlery, some people use chopsticks, some people use hands, some people use bread, some people roll food into little balls and toss it in their mouth, some people struggle to use cutlery at all....different cultures, habits and abilities. The only thing at is 'bad manners' is judging people for the way they eat.
