Man goes into a bar and says "right! drinks all around" and looks at the bartender and says "and have one yourself".Barman says "thankyou sir"
In a while the barman says "that will be 20 dollars".The guy replies "oh i dont have any money".Crash bang ..the barman throws him out on the street.
Undaunted the guy gets up, dusts himself off and goes straight back in.Goes up to the bar and says "right! drinks all around", the bar tender starts walking toward him ...."and NONE for you..you get angry when youre drinking".
