I'm visiting from France. Back home I always eat pizza, fries and smaller burgers with my hands, no big deal.
Recently I went to a nicer restaurant and ordered a burger. I didn't eat it with my hands, not because I cared about looks, but because it was stacked so high I knew it would fall apart at the first bite.
So what's the actual rule here? Is eating with your hands at an upscale place frowned upon, or totally fine?
