He replies, “Oii, your kind ain’t welcomed here so take your drink, mates and fuck off.” He goes back to his mates and says, “We’d better get outta here.” “Nonsense.” replies the mid guy, he’s your typical string. Goes to the barman and same story. Finally the last guy, He’s your typical rope. He burst out, “Fuck this!”. He twits and ties himself whilst messing up his hair.
