You need to decide if a beer or two is worth it. Although it IS legal to drink or go into a bar while carrying, doing so comes with substantial risk.
The previous posts are exactly on point regarding the legal fallout that will follow if you use deadly force and you've got alcohol on board.
If you choose to carry while drinking adult beverages, you have to be aware of and prepared to handle the consequences of interaction with LE. If you are stopped for a traffic offense or involved in an accident and the cop smells alcohol on your breath, he/she is no longer looking for a reason to let you go. You will be run through the Standardized Field Sobriety Tests to determine if you're impaired. I can tell you from experience that way TOO OFTEN, LE will "see" signs of impairment to justify the arrest. That means that even if you have a legal B.A.C. (less than 0.08%), they can and often do still arrest a person for DUI. If you're carrying your weapon, you've just added another criminal charge to the booking sheet. BCI will be notified of the charges and your CCP will most likely be suspended pending the outcome of the criminal matter.
The out of pocket costs will be substantial to prove you were acting within the law and that doesn't factor in the personal stresses you'll have to deal with.
So again, is one or two drinks while carrying worth it? My two cents worth is leave the weapon home or locked up. If you don't like my two cents, you can always pay me the big bucks to defend your rights...
