Reply To: Is it the משגיח’s fault?

Restaurant business has a very low profit margin and high risk of failure. So, probably, yetzer hara to use something cheaper is very high. Still, how often do we have failures like that? Halakha often uses “rov”, not absolute guarantee. Maybe if you buy 3 chickens from 3 different restaurants and then mix you up, you can go by rov?!
