Dated a girl once back in the 80's. She spent the night and the next morning we were going to breakfast and she wanted to go barefoot.
Keep in mind we live in a beach town so bare feet kinda comes with the territory.
That said - for me you don't do that going into a restaurant. Even a small "beach" cafe.
So we parted ways - just over that. She just couldn't accept my POV.
I know hard to believe but I DO have SOME standards!
She had a nice set of hooters on her too!
