For these two individuals, it was about to be a bad night. While it is unclear what started the incident, it is very clear what ended it.
Three individuals can be seen yelling at each other in the video below. One of the men, less than politely, asks the two individuals to leave his personal space. However, he was not obliged.
After the two men began approaching him, the individual swung, eventually knocking one of them to the ground. After a few more moments of shouting, the swinging started up again.
This time, the man managed to knock out one of the individuals encroaching on his personal space. The video can be seen below.
