This thread is not about NC law. It is about OCing where alcohol is sold for on site consumption. NC is mentioned as an example.
That doesn't preclude someone from mentioning other states. Doing so offfers a comparison and shows how various states have addressed this = pointing the way for other states.
In that case I will point out that Utah law does not impose any prohibition on carrying due to the sale or even personal imbibing of alcohol. Utah law
prohibits carrying while intoxicated or under the influence of drugs such that one is not safe to drive a car (0.08% BAC or unable to safely drive a car).
Being a T-totaler I can't claim any expertise in carrying while imbibing. I know drinkers who exercise an abundance of caution and don't drink at all while carrying and don't carry if they are going to or have been drinking. I can't fault them.
As an analogy, I have co workers who will not drink a drop while on company travel if they have to drive. If dinner is within walking distance of the hotel, or they have a non-drinking DD, they will have a couple of drink with dinner and would most certainly still be legal to drive. But their thinking is, "If I'm in a crash for any reason while on company travel, I don't want a drop in my system. It just isn't worth it." Some gun carriers use similar rational while carrying. "If for any reason I have to use the gun, I don't want any question at all about alcohol."
OTOH, I don't personally have any problem with a mature adult having a drink or two while carrying. Any number of things can reduce our personal performance from its peak including illness, being tired, emotional stresses, etc. I don't leave the gun home over these common inhibitors unless/until they reach a point where I don't believe I'm safe carrying. And at that point, I really should not be driving either. So I don't see a problem with someone having a drink or two and carrying with whatever minimal level of impairment might come from a BAC of 0.05% for someone accustomed to alcohol.
Of course, if there are any pinko-commie, tree-hugging, urbanites who love to raise taxes, hate guns, or are small minded religious bigots reading this, the above is all moot since we all know you can't get a drink in Utah anyway, the State is filled with wild Indians and half crazed rednecks, and so visiting Utah is a bad idea, moving here is probably all but fatal with a very miserable existence until the sweet release of death.
Additionally, Utah law gives no special force to gun ban policies at private businesses. The rare restaurant, club, or bar that is hostile to guns can put up signs but they have no legal effect. They can ask someone to leave, and at that point there
might be a trespassing matter. Even there Utah's commercial trespass law sets a higher bar for conviction than for simple trespass on residential private property. Good etiquette pretty much demands that one leave when asked. Civil disobedience gets rather dicey while armed. But, if nobody notices the gun for whatever reason, and doesn't ask the customer to leave, he is golden.
I am not aware of a single eating or drinking establishment in Utah that is hostile to RKBA. A couple of sports arenas are posted, one uses metal detectors sometimes. A couple of movie theaters used to be posted, I'm not sure they still are. Hospitals are all posted, but with the exception of the secure area of mental health facilities (which must provide storage), no violation of law to ignore the signs.
