I'd guess folks are dining at home more often. They may eat frozen pizza instead of pizza hut etc.
I was musing about my diet back in school. I'd eat a bowl of Total for breakfast because it had vitamins. I'd make two baloney sandwiches with mustard, nothing else, for lunch. I'd fix coffee in the lab. Then for dinner I'd do something, maybe grill some chicken and frozen peas. For a real adventure going upscale, I'd drive to the S&S cafeteria in the mall for dinner.
