You know WHO is/are VERY RUDE, in NYC?
TOURISTS and those who just moved there and that has more or less always been the case!
One of the biggest “cons” to living in NYC is that it hosts a very transient population. I remember reading an article commemorating the tenth anniversary of 9/11, and one of the things it pointed out was the astonishing portion of the city’s population (maybe 40% or more) that had moved there since 9/11.
