Has the health inspection system changed for Knoxville restaurants? I don't really keep track of the scores, but I click on it whenever it is on the front page of knoxnews.com and it seems like it has been a long time since I have seen anyone in the "75 or under" category. There used to be restaurants down there all the time. For that matter, I haven't seen anyone below 95 in a long time.
Seems that I recollect an article in the past year that indicated that the Health Dept. had "standardized" their inspection process somewhat. If I recall correctly, it was because different inspectors were conducting inspections differently. I've noticed higher average scores as well.
When you do things right. people won't be sure that you've done anything at all.
