I'm not talking about the left-handed using it the "wrong" way round, or even the way some people hold a knife like a pen rather than, well, a knife.
I've noticed more & more young people, teenagers mainly, using cutlery in frankly bizarre ways such as clasping the fork vertically in a fist & scraping off chunks of food that is pinned by the knife. Usually while leaning sideways onto an elbow at the same time. I notice them in restaurants mostly, as I'm not going round spying through windows, & can only assume they eat with their fingers at home.
