I was a non functioning alcoholic and ran with some rough types in my late teens/early 20s and have both kicked ass and had my ass kicked. Mostly drunken barfights.
One time someone legitimately mistook me for someone else and started cussing at me, so I started cussing back and pushed him to the ground. He got up and did a really neat move actually where he faked a kick and then socked me right in the cheek, knocked me on my ass. I apologized, got up, we figured out the misunderstanding and he bought me a beer.
Got punched over the counter while working at a liquor store. The dude had been 6 times already that day to get our cheapest/highest ABV Beer and was back for more when suddenly he decided the price was too high. He argued with me (working solo at the time) and things escalated to the point where he pooped me in the nose. I was able to dodge most of the force of it due to the distance and his drunkenness, but he got the tip of my nose with a clumsy naymaker.
After he hit me he suddenly had a realization about what he’d done and he ran away as I threatened to call the cops (an empty threat, I live in America and only call the cops when someone might die because calling the American cops might be the cause of someone’s death). Never saw him again.
The kicker is that he’d already paid for his beer when he started the argument and forgot to grab it as he ran.
