I do my best to keep a copy of the final shop submitted. They don't always save nicely. And I write my notes and my narratives in word and save them.
I also have a list of companies that I have learned lower standards than I do. The example you presented is a good example. The one I mentioned earlier is another example. Another example - A company refused to turn in anything negative to the client. This was a bank shop and there were cameras EVERYWHERE. I begged the company to have the video reviewed to confirm that I waited 20-some minutes before I was acknowledged. The company refused. They said that couldn't have happened, therefore, my report was void. I found out later that the report was altered and submitted to the client. Amazing what people leave lying around on their desks... I no longer work for that company.
On the flip side, I have been absolutely amazed by some companies who do turn in the real report to the client, no matter how bad it is! I was once contacted by the client corporate office, with an apology, for what I had experienced and reported to the client. (WOW.) Not pleased that the company gave up my personal information, but it truly illustrated that the truth went to the client and the client cared.
If it wasn't such a negative thing, I would suggest someone start a post to list companies that we have had personal experiences with that won't submit the real report to the client. Or ones that severely alter our reports and we found out about it. (I guess that is kinda like the first, not telling the client the truth, huh?)
