Doing a 3rd party audit bears very little difference to visiting a buffet restaurant (Golden Corral), you go in and take a sample of everything offered that fall into the categories of your taste (plan) at that time. Because of time constraints (available duration) and other factors you selectively choose what to eat, and how much to eat, more of this, less of that and so on including some "tasties". Now, and this is very hard for auditors to comprehend (but not diners) we don't go to the buffet to find stuff that's bad, we go in to find and eat good stuff being surprised when we locate a "nasty" (NC......no it's not what we went in for). In the end we're going to base our opinion (findings) of the whole food line and Buffet on the limited "samples" we ate...........There's no way in H*ll we can taste every single item offered and available and it's the same during an audit, everything is based on what's in the sample and there are and will always be "nasties" and other good stuff outside of that sample, and nothing will ever change that and absolutely nothing can be done to recreate the exact same sample.........It ain't gonna happen!!
If the CB auditor didn't "sample" the right stuff he's gotta visit the buffet again, but only when the buffet is open for business and not any time he chooses to suit his needs unless somewhere it's posted "Open and cooking on demand" (That's where the contract comes in, if the contact doesn't stipulate revisits and the causes of their needs, regardless of the internal CB's rules it has to go by, the stove and lights can stay off and the doors locked).........My personal feeling.
