Many years ago at my own wedding in Williamsburg, my father had someone on the staff of the hall stand at the front door and hand each Ani $10 and asked them not to come in. If they insisted, they were let in, but I’m told that very few came in. They took the $10 and went elsewhere. It cost a total of about $300, and our wedding guests were able to enjoy.
My only question is: Did we take away everyone’s Mitzvas Tzedaka for the night?
