anuran:
Well said. I agree with the approach, and your explanation.
Oomis:
A lot of the amateur shadchanim are not working people but kollel couples (whether they are just married or 40+ years old). They have the time on their hands to do shadchanis and to spend enormous amount of hours on it. However, a lot of them have never worked in a professional environment and do not understand that one gets paid when he or she shows results, not just for effort.
