I got harassed by a guy in a club last year, he grabbed me, then threw me on the floor, bouncers took him out, as I went out for a fag to calm down he was in the foyer I cracked him in the mouth, stupid me!
Broke his teeth, three cuts in my knuckled, got infected and had to go on antibiotics, also got a caution for GBH but they dropped it to Common Assault as I did nothing.
He got nothing, he also popped my ex's nose.
