This is becoming a greater issue. I have been to weddings where the number of expensive Single malt scotches on the boys table rival’s shelves in stores! And they were being emptied!
I went to a Simcha where all the bottles were taken from the public Kiddush table by the boys and when an adult came to take a lechayim the boys were very unhappy. I myself removed a bottle, took it to my table shared some with the adults, who drank a Lechayim, no more. Just to put a dent in their drinking. One of the boys came back to take back “his” bottle. When I said he had enough, he said “I am a responsible adult” I looked at him and said “Apparently you are not!” He then took a new approach and just said “are you drinking that? I said yes, and poured it into an empty glass. (Which was thrown out) He made an issue of gathering up every bottle of booze in the place and walking by trying to catch my eye. (He did not, my wife said something to me afterwards)
It should be noted that HIS PARENTS were there also!
I find this behavior so obnoxious that when I someone points out an available boy on these tables as a potential shidduch, I tell the shadchan, he is not a potential for any of my children! These boys attend what people would call IVY LEAGUE yeshivas. I think it is reprehensible.
I would like to say that I attended an aufruf last week and there was not a single bottle of booze on the boys table. The boys all acted with the utmost derech eretz and remained Sober.
There will be no Booze served at that wedding either!
The only way to address this problem is for adults to take a stand, even if the adult is not related. Get the bottles off of the table. Caterers have no problem with removing booze from tables. Rabbeim should also remove booze from their talmidim’s tables and then when they are back in yeshiva give these guys a shmooz about such behavior.
Will this help? Maybe, maybe not. But it may, and it certainly will be better than doing NOTHING!
