She is lucky that she did not get stopped on the way home after that by the police. Here in Vietnam, they are very active against drinking and driving. They have a zero BAC tolerance. If you have any alcohol in your system they will take your car or your bike and your license
Never saw them but heard they have alcohol wands in Japan, the wave them in the car and I guess they light up with odor of alcohol then it's a big deal. Hopefully a wake up call for her, would suck to not be able to drive
