Kristofer Jonsson, right side, is a deaf chef with a restaurant in Christchurch, New Zealand. He is fluent in New Zealand Sign Language. Kitchen staff loves him because he never screams at them. The irony – the hearing chef (left side) is a screamer, screams at these small errors in the kitchen. You can tell that he is screaming because he closes his eyes while opening his mouth. The deaf chef, by looking at the picture, is a man of peace!
