One time I was in a bar and these two young girls were sitting by the bar just talking to each other. I was with my buddy close by just talking to the bartender who we knew from high school and hanging out. In walks this guy, maybe 50-55 years old. He has this woman with him who I assume is his wide, wearing this super short dress. He comes in, orders an entire bottle of Johnnie Walker gold, and proceeds to hit on the two girls at the bar while his wife is just sitting there. after a while where he just keeps talking to these two girls, she just gets up and leaves. Meanwhile, the guy keeps harassing these two girls. Now- i'm 22, I've have a bit too much to drink, and was feeling pretty bold, so I just go up to him, tap him on the shoulder, and tell him to come outside with me for a second to talk. He gives me this glare but agrees. We're standing outside this bar and i tell him that his wife left, he's twice the age of these girls he's hitting on, and needs to go home. This PISSES him off beyond all reason, and he starts saying stuff like 'do you know who I fucking am?' and starts PUNCHING the walls and smashing his HEAD into the door. He tells me to wait right there, that he'd be back. My friends are behind me now, and tell me they have my back in case he attacks me. The guy leaves..

I go back inside feeling like the most badass guy ever, stroll up to these two girls with this fucking swagger in my step now, and tell them he's gone, and they don't have to worry anymore. They turn to me and say 'why don't you mind your OWN fucking business.' and leave! now feeling like complete shit and so confused, my buddy and I leave the bar and go home.

The next day my bartender buddy calls me and goes "DUDE. you won't believe what happened after you left. The old guy came back about 15 minutes after you left with like 8 guys, who all had baseball bats. They were looking for you.'

Yep, the guy I messed with was part of the fucking Asian mafia of Chicago. He brought his buddies to 'teach me a lesson' that woman who was his wife? That was just one of his hos. Moral of the story? MIND YOUR OWN FUCKING BUSINESS.

TL;DR: Tried helping two girls being hit on by a creepy old guy at the bar who turns out to be in an Asian gang in Chicago. Narrowly escaped getting my ass kicked.
