Because the idea NYC residents hate everyone is media created, and has no correlation to reality.

Do NYC residents curse a lot, and get annoyed by vacationers just standing in the middle of the sidewalks being oblivious to everything around them? Absolutely and they will tell you that. But they also have repeatedly shown in studies to be far more helpful to people than any other city in the US and even in many cities across the world.

Its just like the garbage that NYC is dangerous, which has not been true since the 70-80's when most cities were dangerous due to white flight and a host of other reasons... Its all media portrayed because it makes for fun jokes and stuff... but its not reality to anyone who has actually been there and spent any time there.

I WISHED "southern hospitality" was like NYC hospitality. Since moving to Texas, people are flat out rude as fuck here... and its not the Californians and other transplants... its the natives. Ill never forget the looks I got when I went out of my way to jump a guy stuck at a HEB without any prompting... they seriously though I was after something and I had to tell them no dude, thats just how I was raised.

I have never had to worry about asking for directions or help with my car or something in NYC or NJ... while I would never expect people to go above and beyond, everyone is genuinely helpful and nice as long as you are not going out of your way to ruin their days. Ironically I was even warned by former Texans who I worked with that Southern Hospitality is all bullshit too.
