Seriously.
I was raised old fashioned like. I hold doors open, get out of my chair if one is joining the table, allow them right of way whilst walking, etc.
Fucking nobody says thank you anymore. I thought it was just an LA thing but I noticed it in a few different cities.
From now on Im going to go out of my way to close the door when I see a woman coming. If Im going through one of those swirl doors, once I get into the building Im going to use something to obstruct the movement of the door therefore trapping them inside.
