Syag, I’m afraid you’re judging unfairly based on private thoughts expressed on an anonymous forum. The feeling that one is entitled to be paid for hard work, when halachically owed (and the saying goes that shadchanus gelt is the most kosher money) is quite natural and does not reflect bad middos. I doubt too many shadchanim would be less than gracious in person (or on the phone).
If it was halachically acceptable to give a candy dish, I’m sure AZOI.IS would not have written as he did. And I say this with great confidence now that he has shown that he (I for some reason am assuming it’s a he) is indeed a ba’al middos.
