I have a tendency to hold doors for everyone. I was taught, who ever gets there first holds the door. Well, I get yelled at all the time by the guys I work with because they say it is rude for a woman who is with a group of guys to hold the door for the guys. So we cannot win for losing.
As for people moving out of the way while walking down the street. I did my own experiment. Ever notice that when there is a group of people who are crowding the sidewalk that when you reach them going the opposite side, you have to move for them, even though they could go single file allowing others to pass on the side walk. One day I decided to see how many people would do just that, move for a person who was going the opposite direction. NOT ONE! So now, I don't move to the side if there is a group of people, they can go single file, why should the lone walker have to move for the party of 4 or 5.
Also, I was on a NY bus not long ago and a woman with a baby stroller was struggling to get off the bus. Two (yes two) guys stepped over the stroller to get off the bus and kept walking. It was my GF who said to the men who had exited all the while stepping over the stroller "THANKS FOR HELPING BOYZ" and she and I grabbed the back end of the stroller and the mom and another woman grabbed the front end.
Rude people are every where!
