GREAT! Ask the question! Of course. We’ve bought flowers or otherwise expressed our gratitude to shadchanim (in this case, lay shachanim), and they found it appropriate enough that they came up with names again.
But it is really disingenuous to bounce around such an idea, say that you spoke to rabbanim who will start implementing this in various communities (Watch this space!) then say, nah, all I meant was to get people to start showing hakaras hatov. What gives?
