From the Arizona Departemnt of Public Safety site:
I entered a private business with my concealed handgun and CCW permit. The business did not have any signs posted prohibiting weapons. Shortly thereafter, an employee approached me and said they do not allow firearms in their business and I must take the gun off the premises. Can they do that?
Yes. Arizona law permits private business owners (or their designates) to prohibit weapons from being brought onto their property, whether signs are posted or not. Private businesses are typically non-government operated businesses such as grocery and department stores, convenience stores, laundromats,
banks, office complexes, etc. Failure to obey the request can result in your arrest for trespassing. (ARS 13-1502 / ARS 13-1503)
