"In the age of the camera phone it's a bit weird when you're sitting having dinner in a restaurant and people think they're being very subtle taking a photo while in fact they're being very obvious. When you're in a middle of a mouthful with friends or family and people come up asking for a photograph, that's when you want to say, 'Actually, I'm going to say no; I'd like to finish my meal. This is my time.'"
