While I'm on things I don't like... I really don't understand this idea of "ne'emanus." A tiny percentage of food establishments have the owner completely involved and in control of all food-related operations, from purchasing through prep, cooking, and serving, 100% of the time. They are all relying on hired mashgichim to cover the areas and times when they can't be in all places at once. Once that third party is involved, is his ne'emanus based in his first-hand knowledge that everything is 100% ok, or on his trust that the third parties he hired are doing the job right?
ETA: I don't know why any owner would want to be relied upon. People should be more keen to trust an owner who says, "You can trust everything that comes out of my establishment, because look at who I've hired and what I've invested in to ensure that we keep to X standards."
