I'm not the original Peevee, but I'll respond:
eating food that is sold by weight without paying, placating kids with food when they're not really hungry, (or if they are hungry, why are you shopping at meal time?), the fact that no one looks good shovelling food into their mouths without utensils and napkins while walking...
and the simple fact that North Americans seem incapable of going more than 30 minutes without shoving food in their pie holes. Movie theatres are now more about the food than the movie. Don't get me started on people munching on food during a Broadway show when I've paid a lot of money to hear the dialogue. Or the guy sitting next to me on a 60 minute flight who had to eat a bag of zesty cheese Doritos 12 inches away from my nose. The notion of "hunger" is meaningless to most of us.
