I always told my sons. Take the date out for a nice dinner in a fine restaurant.
#1 You’ll find out if she accepts your kashrut standards and avoid arguments later
#2 You’ll get to see her manners
#3 Even if the date’s a bust you get to enjoy a fine meal of your choice.
Of course JAP (prince or princess) rules apply….daddy will pay
BTW>>>I used this dame dating strategy almost 50 years ago and am very satisfied with the results.
