Where do you get your info? :facepalm: Vault City does not allow booze in their city not NCR. NCR just wants you to keep your weapons away. They don't check you for drugs and booze like Vault City.
from their own prop
* No weapons may be openly carried inside the city limits.
* Persons found under the influence of alcohol or drugs will be arrested.
* Slavery, gambling, and prostitution are not permitted within city limits.
* Ignorance of the law is no excuse. A [censored] will get his/her butt kicked just as fast as a [censored].
* If you can’t live by these laws – then get the hell out cause we don’t want you here!
one could now discuss the actual meaning of "under the influence", but it could put you at the very least in a somehow unpredictable situation when trying to get home from the bar. doubt there will be some sort of taxi waiting :laugh:
