Popa, when my family moved to monsey almost 30 years ago, there was one kosher pizza place. Well, sort of. They kept sneaking in non-kosher cheese.
They lost their hashgacha. People were really upset so they implemented a mashgiach tmidi. Didn’t work because the owner paid off the cheese guy to put stickers on before delivering the cheese that had proper hashgacha.
Be careful of pizza LOL.
