I seldom bother to explain. Most places just think I'm a nut who photographs everything he eats. Besides, 9 out of 10 Roadfood restaurants wouldn't be too impressed if I walked in arm-in-arm with Jacques Pepin, Julia Child, and the restaurant critic from the New York Times and told them we were writing a feature story about their meat loaf. So even when I do tell them why I'm taking pictures (and eating 3 different entrees), it usually doesn't cause more than an indifferent shrug. And that's the way I like it!
