This was more that just being teeded off. This was passed that when you didn't say thank you for holding open the door. That is not normal all the time but there are those. I would have to say a few that will hold the door for you. Man or woman, then to not thank them is rude. Regardless of the age, I have held the door for people. Might not have gotten a thank you but it didn't bother me at all.

Yet I think that way a man thing for it to end up like this. It had to have really been some rather ugly things that they said to one another. For it to go beyond words to violence.

Geez, were both these guys on something?

I hold doors open most of the time, for both genders, and I couldn't care less if the other person thanks me or not. Most do, but I don't complain if they don't.

I only had one instance when I was much younger and neglected this civic duty when the "victim" complained, "Didn't you see me coming?" - the fact was, I didn't, and I informed her, and that was that.

I can see it if the other person was in a wheelchair, or uses a walker or cane, I am more conscientious in those situations, but two fully capable allegedly adult people ...

Maybe all these cell phone waves in the air ...
