A restless Ronnie O'Sullivan crashed out of the UK Championship after losing a final-frame decider to Kyren Wilson in York.
The record seven-time champion frequently sat down in mid-break, complaining of distractions in the two-table arena, and also ordered a photographer to leave.
Nevertheless O'Sullivan reeled off two frames in a row to claw back a two-frame deficit, only for Wilson to reply with a break of 102 in the decider to win 6-5 and seal his place in the semi-finals.
Wilson will face Luca Brecel in the last four after the Belgian breezed to a 6-2 win over Anthony McGill.
O'Sullivan had not seemed at ease all week in York and seemed to leave with a final volley at the spectators at the York Barbican, giving us the snooker equivalent of Roy Keane's infamous 'prawn sandwich' comment.
"I'd rather just sit down and wait. I said to the referee, we're in no rush. I'm here to play snooker and there's no time limit on how long the match takes.
"It doesn't bother me. I play in good venues and bad venues, it is what it is. I don't even care enough to have an opinion on it. It is what it is - just keep eating the smoked salmon and cream cheese."
On the photographer he said: "I've said that unless they have a tripod they are not welcome. It’s not a lot to ask, if you are a cameraman it should be standard stuff to be carrying about so maybe he should go to the professional and get his kit right."
So it was Wilson who rose to the occasion, clenching his fist midway through his final-frame century which sealed a last-four clash against Belgium's Luca Brecel, who beat Anthony McGill 6-2.
Wilson said: "I'm super-proud. At 5-3 things were starting to go a little bit against me and it's only human to start to think your time has gone.
"I'm kind of fighting myself and starting to think I could have won this one, I've let another one slip against him, because I have let a couple slip against Ronnie, so to hold it together and take it out convincingly, there's no better feeling."
Wilson insisted he was not distracted by O'Sullivan's antics, but admitted: "I just wanted to get on with it.
"I understand his reasoning for that. But when the crowd were up on my turn I just got on with it and I did a pretty good job."
