What I have seen would never happen in my kitchen. I go out of my way to make sure raw meats and fresh foods are isolated from each other. There are too many violations to list but one you left out of your summary was finger licking. The fingers go from the sauce to the mouth to the salt and back to your raw food again. Speaking of salt, I've seen Chef Anne Burrell and Paula Deen both go from raw meat to the salt dish repeatedly. I suppose the salt will kill pretty much anything but it's still gross.
