Looking at the states in question, perhaps we should not be surprised, but seriously, how is this a good idea ANYWHERE in this gun-loving, hair-trigger temper, liquored-up society? (NYT):

Happy-hour beers were going for at Past Perfect, a cavernous bar just off this city’s strip of honky-tonks and tourist shops when Adam Ringenberg walked in with a loaded 9-millimeter pistol in the front pocket of his gray slacks.

Mr. Ringenberg, a technology consultant, is one of the state’s nearly 300,000 handgun permit holders who have recently seen their rights greatly expanded by a new law – one of the nation’s first – that allows them to carry loaded firearms into bars and restaurants that serve alcohol.

…The new measures in Tennessee and the three other states come after two landmark Supreme Court rulings that citizens have an individual right – not just in connection with a well-regulated militia – to keep a loaded handgun for home defense.

…State Representative Curry Todd, a Republican who first introduced the guns-in-bars bill here, said that carrying a gun inside a tavern was never the law’s primary intention. Rather, he said, the law lets people defend themselves while walking to and from restaurants.

The purported mitigating factor here is the gun-toter cannot drink alcohol in the establishment. If these laws are challenged in states with big urban city centers and gun restrictions fall by the wayside, you can imagine the chaos that will ensue.
