I had a nearly perfect chicken sandwich for lunch. It was hot, chopped, spicy chicken breast, with melted cheese on it, put in a fresh kaiser roll with lots of mayo, some salt and pepper, a little lettuce, just enough to make the sandwich cool and slippery instead of sticky. It was wrapped in wax paper and blank newsprint, cost $3.50, and was served to me at a walk-in deli at the skinny north end of Central Park. As I was standing at the counter, marvelling at the 9 video cameras in the four-aisle store, a wiry black man slid into the store. He was carrying a wind breaker and placed it on the counter where the man beside the young cashier was counting receipts. The black man launched into a quickly, quietly spoken pitch about how the receipt man could buy not just this jacket but as many as two others, and the price was as little as $30, no $20 dollars for this jacket that normally cost $90. It was a real steal deal, the man said.
