Last fist fight I saw was ages ago back in the 80s....
I worked doing market research surveys in the mall so we were perched right at the escalator in front of one of the department stores. It's was an old mall, one of the first enclosed malls, so the stores weren't all that big. Anyway, this guy and his girlfriend are in the department store and the guy is obviously bored out of his mind watching his girlfriend go through every single garment on the rack. This was the 80s, and while it wasn't common to see men dressed like this where I lived, I figured he must have been in a hair metal band of some sort. They were both wearing zebra stripe spandex pants with high heels and had HUGE 80s hair made in similar styles. We all kind of stared because this guy and his girlfriend looked so much alike. Even their hair color was the same. Compared to the usual freaks that regularly occupied the mall, this couple was pretty innocuous so we didn't pay much attention until some guys from another hair metal band walked by. They stopped and talked amongst themselves.
We could tell right away there was an issue here. The store guy was dressed in white and light colors while the guys in the corridor were all dressed in black leather and spandex though their hair and heels were just as big. One of my coworkers then leaned in close to me and explained that the guy in the store was with a band who had dissed the band in the corridor.
Well.... the guys in the corridor started jeering and making noise causing zebra guy to look up and see these guys. He flipped them off. The black leather boys didn't put up with that and went into the store and started arguing. One of them insulted zebra guy's girlfriend and right at that zebra guy threw a punch.
As soon as zebra guy landed his punch he went right over on his side and into the carousel rack because his spiked heels couldn't support him. It's like his feet just twisted to the side and down he went. The guy he hit stumbled over, into his friends, who managed to hold him up. The torso mannequin on the top of the carousel fell over forward and managed to hit zebra guy. Zebra guy grabs the torso and throws it at leather boy who gets so angry that he tries to pull zebra guy out of the carousel by his shirt. Only he can't because zebra guy weighs more than he does, the shirt rips, and zebra guy counters by pulling leather boy into the center of the rack with him! This causes the whole rack to topple over with a crash and the glass plate in the center crashes down on the tiles and shatters. Zebra girl is no wimp. She grabs the mannequin torso and moves to hit leather boy with it only leather boy's band mates grab her, causing her sweater to tear when she pulls away. She then starts kicking at the guys to try to nail them in the balls. The first guy she aims for jumps back, grabs her ankle, knocking into another friend and then they ALL GO DOWN like dominoes in front of the now destroyed rack while leather boy and zebra guy go at it on the floor, high heels in the air, rolling around in Ladies' Fashion Tops.
And who does the store send to try to fix this? The shoe guy, who we had come to call, Swivel Hips Anton, who is about as delicate as the shoes he sells. He's the only man who works in the store and possibly the only man in the entire mall who appears less butch than the guys rolling around on the floor. Anton just stood there, shouting that the store is calling the security guards and they'd better stop now. Of course they ignore him. Finally one of the band guys gets some sense and begins to pull leather boy off of zebra guy only leather boy can't get up because he keeps falling off his spiked heels. Finally, leather boy manages to stand up, the girl helps zebra guy up, still shouting about what assholes and douchebags the black leather guys were. Zebra guy's got a bloody nose, no discernible shirt left, and his hair is stuck out on the side making him look like an airedale stuck by lightning.
Sadly, before we could see more poodle hair and spandex fly, the security guards arrived and the fight stopped while both parties kept shouting insults at the other. They were all escorted back into the store somewhere and we didn't see what happened. We found out later they were arrested and all of them banned from the mall for life (oh noz!) though that didn't matter much because the Galleria moved in a few years later forcing the old mall to close.
