I missede the deleted mssge. However here is my 2 pence worth.
Andrew I appreciate you are sincere however the following is my experience.
Keep it impersonal you can warn - do not buy a fish with clamped fins.
Shops are ppls livelihoods and every owner/manager, I am sure, is willing to listen to complaints (and compliments). For that is one way that they can improve or better their business. Most business rely on happy customers.
One negative comment could ruin years of work and investment a person has put in. Maybe due to negligence/ignorance of a new employee so I agree the board is not for singleing out one person or shop.,
If I had a complaint I would first go to owner/manager.
Then to consumer complaints or animal welfare.
I always give the owner / manager a chance to put things right. They are human too and suffer from down days and stress gets to us all.
