A Chosid, the KGB, and the Silver Becher

There was a chosid (he said the name, but I don't recall), who once had a "visit" in his house from the KGB. They did a thorough search, and confiscated the one item of value that he owned, which was a silver becher.

The chosid was a very temimus'dige chosid, and he went to the Rebbe Rashab and said that he wanted to go the the KGB headquarters and demand that they return the becher, since this was the only becher he had, and he needed it to make kiddush.

The Rebbe Rashab rejected his plan, saying "ess iz shoyn le'acharei habirur".
