So to answer your question I would be inclined to say NO, for they would have been closed down years ago. So I believe many are staged, or they deliberately find the ones that slipped through the gaps. It is also very difficult to believe an Owner would allow his business to be seen like that, so there must be “rules” or incentives to make the place purposely deliberately as bad as possible.. Just think about your home, if you are expecting guests you will do EXTRA clean up.. This is exactly the same for Michigan Wolverines Back To Back Big Ten Champs Hail To The Victors Shirt, hence why it is important that inspectors give zero warning. It is vital to keep high standards constantly, cleaning is a crap job, it’s boring, none of my workers or even myself enjoy it, but it is vital. If you are really concerned you can always ask to have a quick look in the kitchen..Out of all the places I have owned/run/operated/worked I would have no issues with a customer having a quick look inside. Some of my business had a large glass window dividing the Bakery from the Customers, this was a great and very affective method of ensureing it is clean at all times and the customers can physically see where their food is coming from, the workers likewise are concerned about their appearance and are extra careful. So my advice is if in doubt ASK!
