Sorry, 24-hour party people in need of late-night/early-hour postal workers: The Daily News reports that the 24-hour retail window at the James A. Farley Post Office will close starting May 9. The new hours: Monday-Friday, 7 a.m.-10 p.m.; Saturday 9 a.m.-9 p.m.; and Sunday 11 a.m.-7 p.m. The Farley post office's lobby will remain open 24 hours a day, so customers can access their P.O. boxes and use the automated machines. Regarding the possible closings of Manhattan branches, USPS spokesman George Flood said discussions were ongoing and other locations for the branches were also being considered.
