Lagniappe is gone now, but his memory lives on.
Masking is illegal in Louisiana except on Mardi Gras. It's a misdemeanor, but PC flows from it.http://www.legis.la.gov/legis/Law.aspx?d=78402
Nothing wrong with generating PC. From little things, big busts sometimes follow. But I suspect the sign also has something to do with the "ungentrified" in the area and the armed security guard just inside the door. Welcome to New Orleans...America's coolest third-world city.
A mask IS a good way to get shot down there...
They gonna try to enforce that on Muslim women ? Good luck with that.
