Restaurant Impossible lives up to its name. Diner closes 5 months after renovation.

14. I worked in 5 different restaurants, a ski resort and a caterer

The cleanest walk-ins were at the big chains -- Del Taco. The other end of the scale is pricey (wanna-be) mom-and-pop owned places where the owners don't go into the kitchen or are afraid of their cooks. Generally cleaning out the walk in has to be done at night, after closing because you have to take a lot of stuff out to get at the racks, the floors and the walls so it doesn't happen all that often.

I'm in a small town now and restaurants are only inspected once a year. You can have 7 violations or so each time before there are any consequences at all. Many people who work in kitchens do not understand biology or cross contamination. And whenever I see a place that makes their employees wear laytex gloves I just avoid eating there because you can't even feel the crap on your hands when wearing those gloves and the gloves provide the illusion of healthiness so there is very little hand (glove) washing and plenty of opportunity for cross contamination.
