I dunno. I can't say I have ever encountered it. Maybe we just have very different experiences.
That being said, on balance I find Southern California women a lot more relaxed and nyc women to be more uptight, as a general principle. Then again, nyc is more uptight than SoCal all around, so there you go! ;-)
It seemed to be more the case in Hollywood, and the SF bay area. Both have statistically higher percentages of the population spring-loaded to the full auto pissed position.
That's true. San Francisco is very much like a little Manhattan - a lot of professional people wrapped up the day's business. The 5:00 am shift at the equity trading firm upstairs in my building (men and women alike) routinely closes the elevator door in my face in their hurry to get to work - but I don't attribute it to malice or even rudeness. They are just stuck in their heads - same as the women who snap at men who open doors for them. Unless your male presence is sufficient to snap her out of her default reaction, that's what you'll get.
