In which case, you are frustrating the best efforts of the professional maitre d's.
The best try to seat the ladies so that they are facing the dining area, so as to decorate their restaurant with beautiful faces.
Oh I get it. I’ll often just take the seat given regardless of position, but I keep watch over my shoulder and use mirrors and other parts of the restaurant to keep watch. I’ve been through several tactical training courses that kind of breed it into you.
My wife’s gotten to the point where she just assumes where I’ll sit and takes the opposite. One high-class restaurant we visited on vacation actually asked me to switch with the lady.
A what? What kind of restaurant are we talking about here? ;-)
