The frustration-aggression principle most clearly applies to individuals with higher-than-average levels of blood alcohol.
When people have more alcohol in their blood than what is recommended/allowed, they are likely to exhibit signs of aggression if they are frustrated. They might become violent if they cannot do something/something doesn't go according to their plans, which may not be the case with sober people.
