For the third time this Spring, sections of the Sunday NY Times I purchased from a Jackson Heights store were missing. This time it was the Arts and Leisure section and the Magazine. The paper seemed lighter than usual, so I compared it with their other papers-which were the same weight (so I assume were also missing those sections). Since I’ve had the same problem in other stores/newstands, I assume it reflects a carelesseness by the Times in compiling the sections. Like many people, I depend on the sunday new york times for reading material all week, so its very frustrating to be deprived of, to me, key sections.
