But not in a facility licensed to serve alcohol, and while under the influence of alcohol. I checked, it's illegal.
I was in there last week and a group of four young men, early twenties maybe, were playing pool and drinking beers, and intentionally showing off their handguns strapped to their hips. They continuously tucked the side of their t-shirts into their pants to expose their guns and holsters. Last I knew it was illegal in Maine to carry a gun in a licensed establishment, and while consuming alcohol. I wouldn't want some punk kids messing up a good thing for the Smalls.
Not so much attention given to this one, probably since they weren't "pit bulls" but lovable, cuddly retrievers.
