Two Stories:
1) I know a son of a dentist who told me that a shaddchan once called him and ask for info on how the girls teeth were (know this is true) – this is crazy!! He tells them that not only are they being silly, its also private info between the doc and the patient
2) I know another person who was called as a reference and was asked what they ise on shabbos (paper, plastic or china.
Maybe if people would stop looking into such non-important things and wouild just focus on what is important, this whole “shidduch crisis” would not be around.
