“Gunsmoke” hinted at some things...
Except that Ms Kitty’s saloon was the only wild west one that the girls were proper and innocent. Only working there to get the cowboys to buy drinks. The only thing wrong about the ladies was the bad stereotype other places put on them.
But I diverge. Your premise still holds even in Ms Russell’s establishment.
Once in a while you’ll see one of the girls going up or coming down the stairs with a cowhand. There are also a couple of episodes that have an upstanding rancher falling in love with one of the girls and she is surprised that he would want someone like her.
