It happened in the last frame. Looked likely at the start was going to be a re-rack but Ronnie unnaturally taking two minutes per shot. Earlier a velcro sponsor logo was coming off Allen's waistcoat and Ronnie maintained he was in his eyeliner. Referre said to Allen he had done nothing wrong. Ronnie had a massive opportunity to win that frame at 5-3 but missed such an easy red. Allen cleared up didn't seem bothered and Ronnie no eye contact left the arena.
The interview with Allen nuts and bolts had done nothing wrong, wasn't going to be bullied by O'sullivan. Referre told him he had done nothing wrong. He also said because of it made.him even more determined to clear up which he did.
O'Sullivan said Allen was standing up a fair bit he passed it off till final frame at 5-3 then confronted him about it. Said it was stuff you'd see down the local snooker hall.
That's why when it always comes up on here about Sports Personality of the Year why O Sullivan and Phil Taylor have never won it that it's my opinion they are both liable to say or do anything out of the blue on live television. Just my opinion mind you. No doubting the greatest in their chosen field but as with a lot of geniuses very much unpredictable and capable of anything.
