I was once in 'spoons (I know it says it all really) when a chap on the next table smashed a glass on the table and glassed himself in the forehead and said to his partner, as the blood poured down his face, "are you happy now?!".
Was in the same pub a couple of years earlier,, before it was a Spoons, and a fight broke out. Next thing someone hit another bloke on the back with a chair, just like they used to do in Westerns.
I have long since learned to say no to anyone who suggestions going to said pub
