It's a pretty good bet you're on the wrong side of the equation
I have started to receive information that there is a group or organization that is approaching restaurants face to face with literature and telling them that they are required to post their property. They are selling these restaurants signs that prohibit firearms. There is a possibility that they are representing or “suggesting” that they are government officials and using some degree of pressure to make the restaurant believe, incorrectly, that they have no choice but to post.
Got that? There are people so afraid of others exercising their rights that their willing to mislead people face to face to push their views.
