As I mentioned, I feel VERY wrong about taking food and drink from a shul where I’m not a member at a kiddush or similar function*.
I understand your feeling. In a case where there’s clearly enough food, most ba’lei simcha are more than happy to have anyone who happens to be in the shul partake in the simcha, or even just to enjoy the food.
Do you disagree with me? That’s fine — just please keep the discussion civil.
I thought I did; my apologies if it came across otherwise.
