It’s for a baby.
When I grew up a kiddush was Cake platters herring and soda. Then it evolved into adding cholent and kugel. Then it became normal to have $200 bottles of booze. Then we added $250 meat boards and now on top of that there are also cured fish boards along with casa tequila and 12 flavors of beef jerky. So what’s next.
And yes when someone lets say in the Real estate business will get a bottle from each vendor, a lavish meat board from the employees etc….all just for the kiddush
Boruch Hashem in my shul there's unsaid rules. The max a Kiddush in shul will be 1-2 kugels, 1-3 different flavored herring, 1-2 different types of cake/rugalach and 1-2 bottles of whisky/liquor.
The Kiddush will be max 15-20 minutes and then its all cleaned up for people who want to learn in the Beis Medrash. That means that the most you are spending is $500-600 and those that can't afford more are not embarrassed.
Everyone is entitled to make a kiddush in a hall or at home and they can have whatever they want, but in shul it goes like this.
