Most businesses do not know they are liable, and most do not know if they do not actively check, people can ignore their signs. With a competent conservative 2a city attorney in the family, i know this is correct.
Understand ..... I just do not go where such is posted .... and if I absolutely have to go where the sign is posted I carry anyway.......”F’em” Proper concealed carry sort of makes discovery very very remote.....
Hope yer well.....stay safe !
