My shul has a kiddush club, and I get the concept.
There is nothing hard to understand about men that are bored in shul and go drink with their friends. You are the one with fall for disrespecting your rav, even if he said you can do it.
The whole idea of a kiddush club is immature and disrespectful. That’s why I was able to say what I said. I don’t need to know any details about your shul, we’re not learning a birkas shmuel here- all necessary info is available.
