So basically I was a board game cafe with some friends and some drunk guy and his mates stormed the shop calling everyone pedos and laid on the table while his mate was recording the whole ordeal from outside the shop through the window. My friend stood up and asked him to leave but the drunk guy carried on being annoying and disturbing everyone in the shop causing some ppl to leave. I got frustrated so I took his pint and walked out the door while the drunk guy was being thrown out by me and my friend, I ended up splashing the pint at him while he tried to attack me but his friends dragged him away. What's the ramifications for something like this happening?
