It's been said that "an armed society is a polite society." But I think that it's a Good Thing to prevent folks in bars from wearing shootin' irons -- and so did a lot of towns in the "Old West."

Rule 10: Never Mix Alcohol And Gunpowder. Drilled into me all too close to a a half century ago when I first took up shooting. (My brother used to add to that "...because then your gunpowder's all wet and won't fire.")   At 12 we weren't drinking much alcohol, but we knew what it meant and why the rule was there, and even today we don't take any alcohol until the guns are cleaned and LOCKED away.

Maybe they're afraid of getting short-drinked by the bartender? Maybe they're advertising their need to display big guns because Nature provided them with ones that are so small?

And yes, I have a concealed carry permit. Not that I use it....
