I don’t know if NY’ers are more accepting, but they certainly have more DGAF or are hardened against non-normal things because of exposure to a lot of different things as part of metro life.

I do find people out west to appear to brush off non-normal behavior but start talking about the faux pas as soon as the perpetrator is out of earshot and get judgy. NY’ers might make eye contact, shrug, and/or have a short laugh, then move on.

CA “chill” is just the result of that brush off. Things are NBD because of that appearance, nobody really invests anything in interaction.
