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.
Yea, while I tend to find that level of self absorption unappealing, in itself it is seldom a sign of true malice.
Honestly, I just don't let uptight people into my life. Problem solved. :-)
