Vintage - I don't think that should happen. You will have massive amounts of falangs not knowing in the slightest on how much to give and possible will disrespect the family (future in laws) with the amount given. I think that there should be mediated circumstances because I have heard of the horror stories and Thai women running away from their familes just over this. But the concept that the parents give back the money to start the marriage seems like a good idea.
