“who has not provided her with a service.”
From the shadchans perspective, perhaps spending 30 minutes with you IS a service. Why is the shadchans time any less valuable than yours or mine? Perhaps we should take the analogy to a lawyer one step further. Perhaps if the shadchan was able to charge a $50 fee to meet with a young man or young lady he/she would have the resources to hire an assistant to help answer phone calls, emails, texts, mesages etc. As it is right now, for their initial free meeting all they get is kvetching, whining and complaining in forums such as these.
