She is definitely full of it, like the employee at a gift shop who told me carrying at all in Ocean Shores is in violation of OS ordinances. I posted on their FB page about the incident, and the owner quickly corrected the employees. Managers think that since they are the "authority" figure that they can spout whatever comes to their holophobic little minds to suit their needs. Most people will except their rubbish, and leave it there.
We as a group need to keep on top of these situations as you have, and not let it slide. The important thing is to be very professional in our responses, so they have no misconception that "we" are not the knuckle dragging baby killers the media sometimes portrays us.
