2 second rule…

Yes, if someone is courteous to hold the door open…you walk even quicker and with a slight nod and thank you as you slip through the door.
There is a shared responsibility to keep good manners going forward.

This is spot on. But sometimes I get lazy.

Nod up or nod down ?

I'll hold the door if not holding the door means closing it in their face. That means 5, maybe 6 feet and then I think they're not disabled so open the door like I did. Wimmin and old folks get the courtesy wait and open with a smile.

Manners are becoming a relic of the past, much like Woodrow I hate rude behavior in a man. I won't tolerate it.

Yeah I do the door flip

I do not believe the good manner rules of the elevator are equal to the good manner rules on the street.
I walk straight into an empty elevator and push the door close immediately.

I Try to be as courteous as possible to everyone but especially for olds ,ladies and babies. Now if your one of those little cunts who doesn’t say thank you or give the nod when someone holds the door open for you …. Im looking to set your car on fire with you in it !

I do it all the time and other men do it for me. Just common courtesy, try it some time.

I'm now at the age that people are holding the door open for me.

I almost don't care how far away they are, I'll hold the door. If I'm in too big of a hurry to offer someone basic courtesy, my priorities are off base.

Not sure I completely understand the issue. Was it the door to a bathroom stall at a rest stop?

Or the backdoor
