It happened sometimes, when a bunch of rowdy youths would come into the night spots to create problems. They could get wild and become unruly even during a performance. A staring incident could easily trigger a fight.
These fights usually started when a group was having a good time at a night club, drinking and dancing with their girl friends on the floor, while another group would be staring at these girls. When one party challenged the other, a quarrel would ensue and minor scuffles occurred.
