A friend and I got into an etiquette debate the other day. Here's the question: Is it still good manners to pull out a chair for a woman, so she can sit down at a table? Or is that an outdated and mildly sexist practice?
Also, standing whenever a woman enters the room. I've never seen this happen, but I know that it used to be part of good etiquette.
I think it's still good manners to hold the door open for someone, if someone is right behind you when you're entering a building. I'll even hold the door open for someone who is five seconds away from the door. But I do this for both men and women, even though the old etiquette books say to distinguish between the two.
