When I was growing up we were taught to take a young woman to a restaurant on the first date.
There was only piece of information we needed to know.
How did she treat the waiter and/or waitress.
At the slightest hint that she treated them with hostility, abuse or arrogance, the date was over.
Immediately.
Walk away from the table and leave her stranded over.
I can imagine that works very well.
Actually the same could be said about the man.
How we treat those who we consider beneath us is very revealing.
