Thanks to those who came. Nine people showed, at least before I left.
Saw no static except for an amusing foot-in-mouth experience:
When my wife and I showed up, we were waiting in line to get in a pay, when the kid who was to be our server came up to the girls at the checkout stand, flustered, and said something about, "There's like five guys with guns back there. You know, just because something's legal, doesn't mean you should do it." He was venting to the girls and I lost track of his conversation while I paid, but he could see me in line (couldn't see my gun), and clearly knew that I was listening to him. Another server said something along the lines of "something something it's the law". And the kid sauntered off. Then he clearly had a 'foot in mouth' expression when he saw me go to join the table. Very funny.
Also, according to my wife, the guy sitting behind us with the party of little boys eyed each of us intently whenever we got up, but looked back down to his plate whenever we turned around.
Our server was pretty tense around us the whole time, but I'm sure this 'experience' will get him thinking. No one else in the whole restaurant seemed to care. (And I went to get food three times.)
You know, we should leave a flyer at each of our tables whenever we do something like this.
