The annual Broadway Bites food festival was in full swing at 33rd Street and Broadway. About 30 vendors were selling delicious, but expensive, food at their booths. Hundreds of people were milling about the vendors. The man was carrying a big, plastic bag filled with empty cans. He showed no interest in the vendors or their customers. He was digging through a big, green, metal trashcan. His head went out of sight as he dug deeper. Instead of pulling out an empty can, he pulled out a half‐eaten sandwich.
