Jothar,
I don’t question the subject of the Kol Horeh, but I do question it’s timing. Why did they wait until 2 weeks before Pesach? Did the hotels suddenly develop kashrus and tznius problems?
Had the Kol Koreh been issued two months ago, guests would have been able to get back their deposits and the caterers could have exercised clauses in their contracts to cancel. They still would have taken a loss, but much less than now.
Will the Rabbonim reimburse the guests, the caterers, the Mashichim and wait staff that will lose their jobs?
