And the Reader's Digest Courtesy Study said so:
"Beneath that gruff exterior, New Yorkers really are a polite bunch: 90 percent held the door open, 19 out of 20 store clerks said 'thank you' and 63 percent of men and 47 percent of women helped with the papers. In total, four out of every five people encountered by Reader's Digest passed the courtesy test -- making New York the most courteous city on the list," the survey stated.
