Surprise food inspections, lol. There have been stores and restaurants that have been in business for decades which have never had an inspection. Most of the country has never seen an inspector. There is not enough funding to hire enough inspectors to cover then entire food industry.
Where?
I worked in a restaurant and it was otherwise poorly run. I have no idea how they made money. But one thing they did well was keep everything clean because of those darned food inspections. A bad food inspection will shut the place down and likely put you out of business. So even a poorly run restaurant will at least focus on that.
One reason I left the restaurant business was because of all that endless scrubbing of stainless steel surfaces and pots and pans. I practically rubbed the skin off my hands with steel wool and industrial grade soap keeping everything spotless.
So I'd be interested to hear where food inspections are never done. So I can stay away from them.
