In Orygun it is legal to go into a bar, carrying on your permit, and have a drink.
In Washington it is illegal to set foot in a bar while carrying, but you can have a drink with dinner in the restaurant.
Both states use the same BAC as driving to determine when you should stop.
Neither state has a noticeable problem with permitted carriers getting 3 sheets to the wind.
Me, I can't remember the last time I was in a bar in a state where I had a permit to carry.
