“Nine stores in Manhattan and the Bronx have been hit with $200 fines for leaving their doors open on hot days in the hope that the escaping cool air will lure sweaty customers. They are the first fined as part of a new law passed in 2008. Last year, only warnings were given out. Fines start at $200, and go up to $400 for any further infractions. The legislation states that any business larger than 4,000 square feet or part of a chain with five or more stores in the city must keep doors closed when using an air-conditioning system. A digital thermometer read a refreshing 79 degrees 10 feet away from a Zara’s on 17th Street and Fifth Avenue, despite it being a muggy 97 degrees two blocks away.”
