Rubio's Mexican Grill prohibits firearms on its premise...
Before I went to the movies, I went to Rubio's Mexican Grill and saw this ominous sign... at Mesa Grand plaza in Mesa, Arizona. No other restaurants nearby have the sign but Rubio's.
No firearms post persuant to Arizona Revised Statutes § 4-229 that prohibits carrying firearms into the premise. (A.R.S. Section 4)
(edit) Figures Rubio's is headquartered in Carlsbad, California (between L.A. and San Diego).
(Edit) Two ways to see it - Rubio's franchise manager and corporate policy expressly state anti-gun rights sentiment with the obnoxious "No Firearms" sign (posted on the front and back entrance sides of the premise) and tell affirmatively pro-RKBA Arizona state lawmakers to draft the fair bill to pass and force licensed businesses to allow law-abiding concealed carry licensees to exercise their rights without interference.
