Oh my no, people on the east coast put far to much effort into smalltalk and smiling. The South is infamously bad in that regard, more than any other group of people that I know of, but nearly anywhere on the east coast puts too much value in small talk or smiling for the sake of smiling for my tastes. Even NYC.
The east coast is where I grew up, and where I got sick of people always pretending to be happy and interested in other people. I prefer to keep it sincere.
