Is 'ladies first' still a thing?

I remember one time some lady looked confused when I opened the door and let her go first, now I can open the door and people don't even say thank you, I don't even get the confusion from people anymore 😂

Should I start racing to get to the door first, just get to a random sprint and yell "WAAAIT... me first" heehee.
