When you go out in public and state you are an employee and share proprietary information that you accessed as part of your job there are two options, either you speak for the company or you don't. If you don't then you are fired. If you do (IOW the company is fine with your public statement) you are not fired.
She was not fired. In fact they say the situation was investigated and they found no reason to dispense with her dubious services.
Ergo, she spoke for that Red Lobster franchise at the least and it could be argued that she spoke for corporate as well since they made no move to discipline her or the franchise.
Had to deal with similar situation in my prior life as a cog in the mega-corp wheel. The person was fired as we wished to make it clear that he did not speak for the company.
You made your points well in your post #78 with which I have no problem.
