My city has implemented a grading system for restaurants. The health inspector pops in for a surprise visit and writes down all of the restaurant's violations, then assigns a grade they have to stick in the window so everyone can see. They also post the list of violations on a website so you can find out exactly what awful things are lurking in the kitchen of what used to be your favorite restaurant. The whole grading thing has been more or less a waste of time. Every place gets an A or B, and it's not like I'm going to stop going to the cheap sandwich place because they got a B. I know it's not that clean, that's why it affordable. I'd prefer not to be reminded every time I walk in that I'm eating at a cut rate establishment that doesn't store their meat at proper temperatures.
